2011-10-11md: remove typedefs: mddev_t -> struct mddevNeilBrown
Having mddev_t and 'struct mddev_s' is ugly and not preferred Signed-off-by: NeilBrown <neilb@suse.de>
2011-10-11md: removing typedefs: mdk_rdev_t -> struct md_rdevNeilBrown
The typedefs are just annoying. 'mdk' probably refers to 'md_k.h' which used to be an include file that defined this thing. Signed-off-by: NeilBrown <neilb@suse.de>
2011-10-07md/raid0: convert some printks to pr_debug.NeilBrown
When md assembles a RAID0 array it prints out lots of info which is really just for debugging, so convert that to pr_debug. It also prints out the resulting configuration which could be interesting, so keep that as 'printk' but tidy it up a bit. Signed-off-by: NeilBrown <neilb@suse.de>

2011-09-23md: don't delay reboot by 1 second if no MD devices existDaniel P. Berrange
The md_notify_reboot() method includes a call to mdelay(1000), to deal with "exotic SCSI devices" which are too volatile on reboot. The delay is unconditional. Even if the machine does not have any block devices, let alone MD devices, the kernel shutdown sequence is slowed down. 1 second does not matter much with physical hardware, but with certain virtualization use cases any wasted time in the bootup & shutdown sequence counts for alot. * drivers/md/md.c: md_notify_reboot() - only impose a delay if there was at least one MD device to be stopped during reboot Signed-off-by: Daniel P.

2011-09-21md/bitmap: improve handling of 'allclean'.NeilBrown
The 'allclean' flag is used to cache the fact that there is nothing to do, so we can avoid waking up and scanning the bitmap regularly. The two sorts of pages that might need the attention of the bitmap daemon are BITMAP_PAGE_PENDING and BITMAP_PAGE_NEEDWRITE pages. So make sure allclean reflects exactly when there are none of those. So: set it before scanning all pages with either bit set. clear it whenever these bits are set clear it when we desire not to clear one of these bits. don't clear it any other time. Signed-off-by: NeilBrown <neilb@suse.de>
2011-09-21md/bitmap: rename and tidy up BITMAP_PAGE_CLEANNeilBrown
The flag 'BITMAP_PAGE_CLEAN' has a confusing name as it doesn't mean that the page is clean, but rather that there are counters in the page which allow bits in the bitmap to be cleared - i.e. maybe cleaning can happen. So change it to BITMAP_PAGE_PENDING and fix some irregularities: - Don't set it in bitmap_init_from_disk as bitmap_set_memory_bits sets it when needed - in bitmap_daemon_work, if we find a counter that is '1', but need_sync is set, then set BITMAP_PAGE_PENDING again (it was recently cleared) to ensure we don't forget about this bit. Signed-off-by: NeilBrown <neilb@suse.de>
2011-09-21md: Avoid waking up a thread after it has been freed.NeilBrown
Two related problems: 1/ some error paths call "md_unregister_thread(mddev->thread)" without subsequently clearing ->thread. A subsequent call to mddev_unlock will try to wake the thread, and crash. 2/ Most calls to md_wakeup_thread are protected against the thread disappeared either by: - holding the ->mutex - having an active request, so something else must be keeping the array active. However mddev_unlock calls md_wakeup_thread after dropping the mutex and without any certainty of an active request, so the ->thread could theoretically disappear. So we need a spinlock to provide some protections. So change md_unregister_thread to take a pointer to the thread pointer, and ensure that it always does the required locking, and clears the pointer properly.

2011-09-10md: Fix handling for devices from 2TB to 4TB in 0.90 metadata.NeilBrown
0.90 metadata uses an unsigned 32bit number to count the number of kilobytes used from each device. This should allow up to 4TB per device. However we multiply this by 2 (to get sectors) before casting to a larger type, so sizes above 2TB get truncated. Also we allow rdev->sectors to be larger than 4TB, so it is possible for the array to be resized larger than the metadata can handle. So make sure rdev->sectors never exceeds 4TB when 0.90 metadata is in used. Also the sanity check at the end of super_90_load should include level 1 as it used ->size too. (RAID0 and Linear don't use ->size at all). Reported-by: Pim Zandbergen <P.Zandbergen@macroscoop.nl> Cc: stable@kernel.org Signed-off-by: NeilBrown <neilb@suse.de>
2011-09-10md/raid1,10: Remove use-after-free bug in make_request.NeilBrown
A single request to RAID1 or RAID10 might result in multiple requests if there are known bad blocks that need to be avoided. To detect if we need to submit another write request we test: if (sectors_handled < (bio->bi_size >> 9)) { However this is after we call **_write_done() so the 'bio' no longer belongs to us - the writes could have completed and the bio freed. So move the **_write_done call until after the test against bio->bi_size. This addresses https://bugzilla.kernel.org/show_bug.cgi?id=41862 Reported-by: Bruno Wolff III <bruno@wolff.to> Tested-by: Bruno Wolff III <bruno@wolff.to> Signed-off-by: NeilBrown <neilb@suse.de>
2011-09-10md/raid10: unify handling of write completion.NeilBrown
A write can complete at two different places: 1/ when the last member-device write completes, through raid10_end_write_request 2/ in make_request() when we remove the initial bias from ->remaining. These two should do exactly the same thing and the comment says they do, but they don't. So factor the correct code out into a function and call it in both places. This makes the code much more similar to RAID1. The difference is only significant if there is an error, and they usually take a while, so it is unlikely that there will be an error already when make_request is completing, so this is unlikely to cause real problems.

2011-08-31md/raid5: fix a hang on device failure.NeilBrown
Waiting for a 'blocked' rdev to become unblocked in the raid5d thread cannot work with internal metadata as it is the raid5d thread which will clear the blocked flag. This wasn't a problem in 3.0 and earlier as we only set the blocked flag when external metadata was used then. However we now set it always, so we need to be more careful. Signed-off-by: NeilBrown <neilb@suse.de>
2011-08-30md: fix clearing of 'blocked' flag in the presence of bad blocks.NeilBrown
When the 'blocked' flag on a device is cleared while there are unacknowledged bad blocks we must fail the device. This is needed for backwards compatability of the interface. The code currently uses the wrong test for "unacknowledged bad blocks exist". Change it to the right test. Signed-off-by: NeilBrown <neilb@suse.de>
2011-08-25md/linear: avoid corrupting structure while waiting for rcu_free to complete.NeilBrown

2011-08-25md: use REQ_NOIDLE flag in md_super_write()Namhyung Kim
Queue idling is used for the anticipation of immediate sequencial I/O's but md_super_write() is a kind of one- shot operation, coupled with md_super_wait(), so the idling in this case will be just a waste of time. Specifying REQ_NOIDLE prevents it. Instead of adding the flag to submit_bio() directly, use pre-defined macro WRITE_FLUSH_FUA.

2011-08-25md: ensure changes to 'write-mostly' are reflected in metadata.NeilBrown
The 'write-mostly' flag can be changed through sysfs. With 0.90 metadata, those changes are reflected in the metadata. For 1.x metadata, they aren't. So fix super_1_sync to record 'write-mostly' status. Signed-off-by: NeilBrown <neilb@suse.de>
2011-08-25md: report failure if a 'set faulty' request doesn't.NeilBrown
Sometimes a device will refuse to be set faulty. e.g. RAID1 will never let the last working device become faulty.

However starting with Ivybridge, the register defaults to 0x2800 out of reset, meaning that to invalidate the TLB we need to use PIPE_CONTROL.

Currently, error handling code in this function calls the function sata_dwc_port_stop, but this function has essentially no effect if hsdevp has not been stored in ap, which is the case throughout this function. The only effect is to print a debugging message including ap->print_id. The code is rewritten to not call sata_dwc_port_stop, but instead to jump to a local label that prints the original error message and the print_id information. In the case where hsdevp has been already allocated (but not yet stored in ap), this value is freed as well.
