Subject: [XFS] find_exported_dentry(). XFS does not need to use this symbol
as it is provided by a vector through the superblock export operations when
the filesystem is exported by NFS. The fix is to call that vector instead of
using the exported symbol directly.

Subject: [XFS] On machines with more than 8 cpus, when running parallel I/O
threads, the incore superblock lock becomes the limiting factor for buffered
write throughput. Make the contended fields in the incore superblock use
per-cpu counters so that there is no global lock to limit scalability.

+ * Per-cpu incore superblock counters
+ *
+ * Simple concept, difficult implementation
+ *
+ * Basically, replace the incore superblock counters with a distributed per cpu
+ * counter for contended fields (e.g. free block count).
+ *
+ * Difficulties arise in that the incore sb is used for ENOSPC checking, and
+ * hence needs to be accurately read when we are running low on space. Hence
+ * there is a method to enable and disable the per-cpu counters based on how
+ * much "stuff" is available in them.
+ *
+ * Basically, a counter is enabled if there is enough free resource to justify
+ * running a per-cpu fast-path. If the per-cpu counter runs out (i.e. a local
+ * ENOSPC), then we disable the counters to synchronise all callers and
+ * re-distribute the available resources.
+ *
+ * If, once we redistributed the available resources, we still get a failure,
+ * we disable the per-cpu counter and go through the slow path.
+ *
+ * The slow path is the current xfs_mod_incore_sb() function. This means that
+ * when we disable a per-cpu counter, we need to drain it's resources back to
+ * the global superblock. We do this after disabling the counter to prevent
+ * more threads from queueing up on the counter.
+ *
+ * Essentially, this means that we still need a lock in the fast path to enable
+ * synchronisation between the global counters and the per-cpu counters. This
+ * is not a problem because the lock will be local to a CPU almost all the time
+ * and have little contention except when we get to ENOSPC conditions.
+ *
+ * Basically, this lock becomes a barrier that enables us to lock out the fast
+ * path while we do things like enabling and disabling counters and
+ * synchronising the counters.
+ *
+ * Locking rules:
+ *
+ * 1. XFS_SB_LOCK() before picking up per-cpu locks
+ * 2. per-cpu locks always picked up via for_each_online_cpu() order
+ * 3. accurate counter sync requires XFS_SB_LOCK + per cpu locks
+ * 4. modifying per-cpu counters requires holding per-cpu lock
+ * 5. modifying global counters requires holding XFS_SB_LOCK
+ * 6. enabling or disabling a counter requires holding the XFS_SB_LOCK
+ * and _none_ of the per-cpu locks.
+ *
+ * Disabled counters are only ever re-enabled by a balance operation
+ * that results in more free resources per CPU than a given threshold.
+ * To ensure counters don't remain disabled, they are rebalanced when
+ * the global resource goes above a higher threshold (i.e. some hysteresis
+ * is present to prevent thrashing).

Subject: [XFS] 929045 567344 This mod re-organizes some of the in-core file
extent code to prepare for an upcoming mod which will introduce multi-level
in-core extent allocations. Although the in-core extent management is using a
new code path in this mod, the functionality remains the same. Major changes
include: - Introduce 10 new subroutines which re-orgainze the existing
code but do NOT change functionality: xfs_iext_get_ext()
xfs_iext_insert() xfs_iext_add() xfs_iext_remove()
xfs_iext_remove_inline() xfs_iext_remove_direct()
xfs_iext_realloc_direct() xfs_iext_direct_to_inline()
xfs_iext_inline_to_direct() xfs_iext_destroy() - Remove 2 subroutines
(functionality moved to new subroutines above): xfs_iext_realloc()
-replaced by xfs_iext_add() and xfs_iext_remove()
xfs_bmap_insert_exlist() - replaced by xfs_iext_insert()
xfs_bmap_delete_exlist() - replaced by xfs_iext_remove() - Replace all
hard-coded (indexed) extent assignments with a call to xfs_iext_get_ext() -
Replace all extent record pointer arithmetic (ep++, ep--, base + lastx,..)
with calls to xfs_iext_get_ext() - Update comments to remove the idea of a
single "extent list" and introduce "extent record" terminology instead

From: Mandy Kirkconnell <alkirkco@sgi.com>

Subject: [XFS] 929045 567344 This mod introduces multi-level in-core file
extent functionality, building upon the new layout introduced in mod
xfs-linux:xfs-kern:207390a. The new multi-level extent allocations are only
required for heavily fragmented files, so the old-style linear extent list is
used on files until the extents reach a pre-determined size of 4k. 4k buffers
are used because this is the system page size on Linux i386 and systems with
larger page sizes don't seem to gain much, if anything, by using their native
page size as the extent buffer size. Also, using 4k extent buffers everywhere
provides a consistent interface for CXFS across different platforms. The 4k
extent buffers are managed by an indirection array (xfs_ext_irec_t) which is
basically just a pointer array with a bit of extra information to keep track
of the number of extents in each buffer as well as the extent offset of each
buffer. Major changes include: - Add multi-level in-core file extent
functionality to the xfs_iext_ subroutines introduced in mod:
xfs-linux:xfs-kern:207390a - Introduce 13 new subroutines which add
functionality for multi-level in-core file extents:
xfs_iext_add_indirect_multi() xfs_iext_remove_indirect()
xfs_iext_realloc_indirect() xfs_iext_indirect_to_direct()
xfs_iext_bno_to_irec() xfs_iext_idx_to_irec() xfs_iext_irec_init()
xfs_iext_irec_new() xfs_iext_irec_remove() xfs_iext_irec_compact()
xfs_iext_irec_compact_pages() xfs_iext_irec_compact_full()
xfs_iext_irec_update_extoffs()

From 8867bc9bf0aed7181aa72c7c938c6ce830b75166 Mon Sep 17 00:00:00 2001
From: Mandy Kirkconnell <alkirkco@sgi.com>
Date: Fri, 17 Mar 2006 17:25:04 +1100
Subject: [XFS] There are a few problems with the new
xfs_bmap_search_multi_extents() wrapper function that I introduced in mod
xfs-linux:xfs-kern:207393a. The function was added as a wrapper around
xfs_bmap_do_search_extents() to avoid breaking the top-of-tree CXFS
interface. The idea of the function was basically to extract the target
extent buffer (if muli- level extent allocation mode), then call
xfs_bmap_do_search_extents() with either a pointer to the first extent in the
target buffer or a pointer to the first extent in the file, depending on
which extent mode was being used. However, in addition to locating the
target extent record for block bno, xfs_bmap_do_search_extents() also sets
four parameters needed by the caller: *lastx, *eofp, *gotp, *prevp. Passing
only the target extent buffer to xfs_bmap_do_search_extents() causes *eofp to
be set incorrectly if the extent is at the end of the target list but there
are actually more extents in the next er_extbuf. Likewise, if the extent is
the first one in the buffer but NOT the first in the file, *prevp is
incorrectly set to NULL. Adding the needed functionality to
xfs_bmap_search_multi_extents() to re-set any incorrectly set fields is
redundant and makes the call to xfs_bmap_do_search_extents() not make much
sense when multi-level extent allocation mode is being used. This mod
basically extracts the two functional components from
xfs_bmap_do_search_extents(), with the intent of obsoleting/removing
xfs_bmap_do_search_extents() after the CXFS mult-level in-core extent changes
are checked in. The two components are: 1) The binary search to locate the
target extent record, and 2) Setting the four parameters needed by the caller
(*lastx, *eofp, *gotp, *prevp). Component 1: I created a new function in
xfs_inode.c called xfs_iext_bno_to_ext(), which executes the binary search to
find the target extent record. xfs_bmap_search_multi_extents() has been
modified to call xfs_iext_bno_to_ext() rather than
xfs_bmap_do_search_extents(). Component 2: The parameter setting
functionality has been added to xfs_bmap_search_multi_extents(), eliminating
the need for xfs_bmap_do_search_extents(). These changes make the removal of
xfs_bmap_do_search_extents() trival once the CXFS changes are in place. They
also allow us to maintain the current XFS interface, using the new search
function introduced in mod xfs-linux:xfs-kern:207393a.

cgit v1.2.3-70-g09d2
From 9fa8046f50bcb88ab9183ee1f22de5adc42bf92a Mon Sep 17 00:00:00 2001
From: Yingping Lu <yingping@sgi.com>
Date: Wed, 22 Mar 2006 12:44:35 +1100
Subject: [XFS] Fixing the error caused by the conflict between DIO Write's
conversion and concurrent truncate operations. Use vn_iowait to wait for the
completion of any pending DIOs. Since the truncate requires exclusive IOLOCK,
so this blocks any further DIO operations since DIO write also needs
exclusive IOBLOCK. This serves as a barrier and prevent any potential
starvation.

From b20a35035f983f4ac7e29c4a68f30e43510007e0 Mon Sep 17 00:00:00 2001
From: Christoph Lameter <clameter@sgi.com>

Subject: [PATCH] page migration reorg
Centralize the page migration functions in anticipation of additional
tinkering. Creates a new file mm/migrate.c
1. Extract buffer_migrate_page() from fs/buffer.c
2. Extract central migration code from vmscan.c
3. Extract some components from mempolicy.c
4. Export pageout() and remove_from_swap() from vmscan.c
5. Make it possible to configure NUMA systems without page migration
and non-NUMA systems with page migration.
I had to so some #ifdeffing in mempolicy.c that may need a cleanup.

Subject: [PATCH] more for_each_cpu() conversions
When we stop allocating percpu memory for not-possible CPUs we must not touch
the percpu data for not-possible CPUs at all. The correct way of doing this
is to test cpu_possible() or to use for_each_cpu().
This patch is a kernel-wide sweep of all instances of NR_CPUS. I found very
few instances of this bug, if any. But the patch converts lots of open-coded
test to use the preferred helper macros.
