- * in-memory bitmap:
- *
- * Use 16 bit block counters to track pending writes to each "chunk".
- * The 2 high order bits are special-purpose, the first is a flag indicating
- * whether a resync is needed.  The second is a flag indicating whether a
- * resync is active.
- * This means that the counter is actually 14 bits:
- *
- * +--------+--------+------------------------------------------------+
- * | resync | resync |               counter                          |
- * | needed | active |                                                |
- * |  (0-1) |  (0-1) |              (0-16383)                         |
- * +--------+--------+------------------------------------------------+
- *
- * The "resync needed" bit is set when:
- *    a '1' bit is read from storage at startup.
- *    a write request fails on some drives
- *    a resync is aborted on a chunk with 'resync active' set
- * It is cleared (and resync-active set) when a resync starts across all drives
- * of the chunk.
- *
- *
- * The "resync active" bit is set when:
- *    a resync is started on all drives, and resync_needed is set.
- *       resync_needed will be cleared (as long as resync_active wasn't already set).
- * It is cleared when a resync completes.
- *
- * The counter counts pending write requests, plus the on-disk bit.
- * When the counter is '1' and the resync bits are clear, the on-disk
- * bit can be cleared aswell, thus setting the counter to 0.
- * When we set a bit, or in the counter (to start a write), if the fields is
- * 0, we first set the disk bit and set the counter to 1.
- *
- * If the counter is 0, the on-disk bit is clear and the stipe is clean
- * Anything that dirties the stipe pushes the counter to 2 (at least)
- * and sets the on-disk bit (lazily).
- * If a periodic sweep find the counter at 2, it is decremented to 1.
- * If the sweep find the counter at 1, the on-disk bit is cleared and the
- * counter goes to zero.
- *
- * Also, we'll hijack the "map" pointer itself and use it as two 16 bit block
- * counters as a fallback when "page" memory cannot be allocated:
- *
- * Normal case (page memory allocated):
- *
- *     page pointer (32-bit)
- *
- *     [ ] ------+
- *               |
- *               +-------> [   ][   ]..[   ] (4096 byte page == 2048 counters)
- *                          c1   c2    c2048
- *
- * Hijacked case (page memory allocation failed):
- *
- *     hijacked page pointer (32-bit)
- *
- *     [		  ][		  ] (no page memory allocated)
- *      counter #1 (16-bit) counter #2 (16-bit)

-/*
- *
- * Each stripe contains one buffer per disc.  Each buffer can be in
- * one of a number of states stored in "flags".  Changes between
- * these states happen *almost* exclusively under a per-stripe
- * spinlock.  Some very specific changes can happen in bi_end_io, and
- * these are not protected by the spin lock.
- *
- * The flag bits that are used to represent these states are:
- *   R5_UPTODATE and R5_LOCKED
- *
- * State Empty == !UPTODATE, !LOCK
- *        We have no data, and there is no active request
- * State Want == !UPTODATE, LOCK
- *        A read request is being submitted for this block
- * State Dirty == UPTODATE, LOCK
- *        Some new data is in this buffer, and it is being written out
- * State Clean == UPTODATE, !LOCK
- *        We have valid data which is the same as on disc
- *
- * The possible state transitions are:
- *
- *  Empty -> Want   - on read or write to get old data for  parity calc
- *  Empty -> Dirty  - on compute_parity to satisfy write/sync request.(RECONSTRUCT_WRITE)
- *  Empty -> Clean  - on compute_block when computing a block for failed drive
- *  Want  -> Empty  - on failed read
- *  Want  -> Clean  - on successful completion of read request
- *  Dirty -> Clean  - on successful completion of write request
- *  Dirty -> Clean  - on failed write
- *  Clean -> Dirty  - on compute_parity to satisfy write/sync (RECONSTRUCT or RMW)
- *
- * The Want->Empty, Want->Clean, Dirty->Clean, transitions
- * all happen in b_end_io at interrupt time.
- * Each sets the Uptodate bit before releasing the Lock bit.
- * This leaves one multi-stage transition:
- *    Want->Dirty->Clean
- * This is safe because thinking that a Clean buffer is actually dirty
- * will at worst delay some action, and the stripe will be scheduled
- * for attention after the transition is complete.
- *
- * There is one possibility that is not covered by these states.  That
- * is if one drive has failed and there is a spare being rebuilt.  We
- * can't distinguish between a clean block that has been generated
- * from parity calculations, and a clean block that has been
- * successfully written to the spare ( or to parity when resyncing).
- * To distingush these states we have a stripe bit STRIPE_INSYNC that
- * is set whenever a write is scheduled to the spare, or to the parity
- * disc if there is no spare.  A sync request clears this bit, and
- * when we find it set with no buffers locked, we know the sync is
- * complete.
- *
- * Buffers for the md device that arrive via make_request are attached
- * to the appropriate stripe in one of two lists linked on b_reqnext.
- * One list (bh_read) for read requests, one (bh_write) for write.
- * There should never be more than one buffer on the two lists
- * together, but we are not guaranteed of that so we allow for more.
- *
- * If a buffer is on the read list when the associated cache buffer is
- * Uptodate, the data is copied into the read buffer and it's b_end_io
- * routine is called.  This may happen in the end_request routine only
- * if the buffer has just successfully been read.  end_request should
- * remove the buffers from the list and then set the Uptodate bit on
- * the buffer.  Other threads may do this only if they first check
- * that the Uptodate bit is set.  Once they have checked that they may
- * take buffers off the read queue.
- *
- * When a buffer on the write list is committed for write it is copied
- * into the cache buffer, which is then marked dirty, and moved onto a
- * third list, the written list (bh_written).  Once both the parity
- * block and the cached buffer are successfully written, any buffer on
- * a written list can be returned with b_end_io.
- *
- * The write list and read list both act as fifos.  The read list is
- * protected by the device_lock.  The write and written lists are
- * protected by the stripe lock.  The device_lock, which can be
- * claimed while the stipe lock is held, is only for list
- * manipulations and will only be held for a very short time.  It can
- * be claimed from interrupts.
- *
- *
- * Stripes in the stripe cache can be on one of two lists (or on
- * neither).  The "inactive_list" contains stripes which are not
- * currently being used for any request.  They can freely be reused
- * for another stripe.  The "handle_list" contains stripes that need
- * to be handled in some way.  Both of these are fifo queues.  Each
- * stripe is also (potentially) linked to a hash bucket in the hash
- * table so that it can be found by sector number.  Stripes that are
- * not hashed must be on the inactive_list, and will normally be at
- * the front.  All stripes start life this way.
- *
- * The inactive_list, handle_list and hash bucket lists are all protected by the
- * device_lock.
- *  - stripes on the inactive_list never have their stripe_lock held.
- *  - stripes have a reference counter. If count==0, they are on a list.
- *  - If a stripe might need handling, STRIPE_HANDLE is set.
- *  - When refcount reaches zero, then if STRIPE_HANDLE it is put on
- *    handle_list else inactive_list
- *
- * This, combined with the fact that STRIPE_HANDLE is only ever
- * cleared while a stripe has a non-zero count means that if the
- * refcount is 0 and STRIPE_HANDLE is set, then it is on the
- * handle_list and if recount is 0 and STRIPE_HANDLE is not set, then
- * the stripe is on inactive_list.
- *
- * The possible transitions are:
- *  activate an unhashed/inactive stripe (get_active_stripe())
- *     lockdev check-hash unlink-stripe cnt++ clean-stripe hash-stripe unlockdev
- *  activate a hashed, possibly active stripe (get_active_stripe())
- *     lockdev check-hash if(!cnt++)unlink-stripe unlockdev
- *  attach a request to an active stripe (add_stripe_bh())
- *     lockdev attach-buffer unlockdev
- *  handle a stripe (handle_stripe())
- *     lockstripe clrSTRIPE_HANDLE ...
- *		(lockdev check-buffers unlockdev) ..
- *		change-state ..
- *		record io/ops needed unlockstripe schedule io/ops
- *  release an active stripe (release_stripe())
- *     lockdev if (!--cnt) { if  STRIPE_HANDLE, add to handle_list else add to inactive-list } unlockdev
- *
- * The refcount counts each thread that have activated the stripe,
- * plus raid5d if it is handling it, plus one for each active request
- * on a cached buffer, and plus one if the stripe is undergoing stripe
- * operations.
- *
- * Stripe operations are performed outside the stripe lock,
- * the stripe operations are:
- * -copying data between the stripe cache and user application buffers
- * -computing blocks to save a disk access, or to recover a missing block
- * -updating the parity on a write operation (reconstruct write and
- *  read-modify-write)
- * -checking parity correctness
- * -running i/o to disk
- * These operations are carried out by raid5_run_ops which uses the async_tx
- * api to (optionally) offload operations to dedicated hardware engines.
- * When requesting an operation handle_stripe sets the pending bit for the
- * operation and increments the count.  raid5_run_ops is then run whenever
- * the count is non-zero.
- * There are some critical dependencies between the operations that prevent some
- * from being requested while another is in flight.
- * 1/ Parity check operations destroy the in cache version of the parity block,
- *    so we prevent parity dependent operations like writes and compute_blocks
- *    from starting while a check is in progress.  Some dma engines can perform
- *    the check without damaging the parity block, in these cases the parity
- *    block is re-marked up to date (assuming the check was successful) and is
- *    not re-read from disk.
- * 2/ When a write operation is requested we immediately lock the affected
- *    blocks, and mark them as not up to date.  This causes new read requests
- *    to be held off, as well as parity checks and compute block operations.
- * 3/ Once a compute block operation has been requested handle_stripe treats
- *    that block as if it is up to date.  raid5_run_ops guaruntees that any
- *    operation that is dependent on the compute block result is initiated after
- *    the compute block completes.

- * Plugging:
- *
- * To improve write throughput, we need to delay the handling of some
- * stripes until there has been a chance that several write requests
- * for the one stripe have all been collected.
- * In particular, any write request that would require pre-reading
- * is put on a "delayed" queue until there are no stripes currently
- * in a pre-read phase.  Further, if the "delayed" queue is empty when
- * a stripe is put on it then we "plug" the queue and do not process it
- * until an unplug call is made. (the unplug_io_fn() is called).
- *
- * When preread is initiated on a stripe, we set PREREAD_ACTIVE and add
- * it to the count of prereading stripes.
- * When write is initiated, or the stripe refcnt == 0 (just in case) we
- * clear the PREREAD_ACTIVE flag and decrement the count
- * Whenever the 'handle' queue is empty and the device is not plugged, we
- * move any strips from delayed to handle and clear the DELAYED flag and set
- * PREREAD_ACTIVE.
- * In stripe_handle, if we find pre-reading is necessary, we do it if
- * PREREAD_ACTIVE is set, else we set DELAYED which will send it to the delayed queue.
- * HANDLE gets cleared if stripe_handle leave nothing locked.

+ * 'subsystem_event' notation is fine.
+ *
+ * Think about this whole construct as the
+ * 'trace_sched_switch() function' from now on.
+ *
+ *
+ *  TRACE_EVENT(sched_switch,
+ *
+ *	*
+ *	* A function has a regular function arguments
+ *	* prototype, declare it via TP_PROTO():
+ *	*
+ *
+ *	TP_PROTO(struct rq *rq, struct task_struct *prev,
+ *		 struct task_struct *next),
+ *
+ *	*
+ *	* Define the call signature of the 'function'.
+ *	* (Design sidenote: we use this instead of a
+ *	*  TP_PROTO1/TP_PROTO2/TP_PROTO3 ugliness.)
+ *	*
+ *
+ *	TP_ARGS(rq, prev, next),
+ *
+ *	*
+ *	* Fast binary tracing: define the trace record via
+ *	* TP_STRUCT__entry(). You can think about it like a
+ *	* regular C structure local variable definition.
+ *	*
+ *	* This is how the trace record is structured and will
+ *	* be saved into the ring buffer. These are the fields
+ *	* that will be exposed to user-space in
+ *	* /debug/tracing/events/<*>/format.
+ *	*
+ *	* The declared 'local variable' is called '__entry'
+ *	*
+ *	* __field(pid_t, prev_prid) is equivalent to a standard declariton:
+ *	*
+ *	*	pid_t	prev_pid;
+ *	*
+ *	* __array(char, prev_comm, TASK_COMM_LEN) is equivalent to:
+ *	*
+ *	*	char	prev_comm[TASK_COMM_LEN];
+ *	*
+ *
+ *	TP_STRUCT__entry(
+ *		__array(	char,	prev_comm,	TASK_COMM_LEN	)
+ *		__field(	pid_t,	prev_pid			)
+ *		__field(	int,	prev_prio			)
+ *		__array(	char,	next_comm,	TASK_COMM_LEN	)
+ *		__field(	pid_t,	next_pid			)
+ *		__field(	int,	next_prio			)
+ *	),
+ *
+ *	*
+ *	* Assign the entry into the trace record, by embedding
+ *	* a full C statement block into TP_fast_assign(). You
+ *	* can refer to the trace record as '__entry' -
+ *	* otherwise you can put arbitrary C code in here.
+ *	*
+ *	* Note: this C code will execute every time a trace event
+ *	* happens, on an active tracepoint.
+ *	*
+ *
+ *	TP_fast_assign(
+ *		memcpy(__entry->next_comm, next->comm, TASK_COMM_LEN);
+ *		__entry->prev_pid	= prev->pid;
+ *		__entry->prev_prio	= prev->prio;
+ *		memcpy(__entry->prev_comm, prev->comm, TASK_COMM_LEN);
+ *		__entry->next_pid	= next->pid;
+ *		__entry->next_prio	= next->prio;
+ *	)
+ *
+ *	*
+ *	* Formatted output of a trace record via TP_printk().
+ *	* This is how the tracepoint will appear under ftrace
+ *	* plugins that make use of this tracepoint.
+ *	*
+ *	* (raw-binary tracing wont actually perform this step.)
+ *	*
+ *
+ *	TP_printk("task %s:%d [%d] ==> %s:%d [%d]",
+ *		__entry->prev_comm, __entry->prev_pid, __entry->prev_prio,
+ *		__entry->next_comm, __entry->next_pid, __entry->next_prio),
+ *
+ * );
+ *
+ * This macro construct is thus used for the regular printk format
+ * tracing setup, it is used to construct a function pointer based
+ * tracepoint callback (this is used by programmatic plugins and
+ * can also by used by generic instrumentation like SystemTap), and
+ * it is also used to expose a structured trace record in
+ * /debug/tracing/events/.
