Gah. I ended up amending the commit and updating it with the comment.

Yeah, sorry about that.
It occurred to me later on.
I initially converted the sgi-mod (undo mod) to a git commit and
then discovered git-revert and thought, hey I'll use that
instead but then forgot to add all the text into it.
D'oh. Thanks for the fixup.

[GIT PULL] XFS update for 2.6.23 - revert a commit

2007-10-01 Thread Tim Shimmin
Hi Linus,

A problem has been found for the XFS commit 
b394e43e995d08821588a22561c6a71a63b4ff27
and it needs to be reverted.
It has the potential for worse corruption than what it is meant to fix.

Please pull from the for-linus branch:
git pull git://oss.sgi.com:8090/xfs/xfs-2.6.git for-linus

Lachlan's description:
This fix is for a problem that has been in XFS since day one.
[XFS] Avoid replaying inode buffer initialisation log items if on-disk 
version is newer.

It tries to fix an issue where log replay is replaying an inode cluster
initialisation transaction that should not be replayed because the inode
cluster on disk is more up to date.  Since we don't log file sizes (we
rely on inode flushing to get them to disk) then we can't just replay
all the transations in the log and expect the inode to be completely
restored.  We lose file size updates.  Unfortunately this fix is causing
more (serious) problems than it is fixing so please don't push this one
back just yet.

This will update the following files:

[GIT PULL] XFS update for 2.6.23

One for harmless sparse warnings and one which can prevent
crashes on 32 bit boxes using filestreams.

[XFS] fix valid but harmless sparse warning

The new xlog_recover_do_reg_buffer checks call be16_to_cpu on di_gen which
is a 32bit value so sparse rightly complains. Fortunately the warning is
harmless because we don't care for the value, but only whether it's
non-NULL. Due to that fact we can simply kill the endian swaps on this and
the previous di_mode check entirely.

[XFS] fix filestreams on 32-bit boxes

xfs_filestream_mount() sets up an mru cache with:
  err = xfs_mru_cache_create(&mp->m_filestream, lifetime, grp_count,
  (xfs_mru_cache_free_func_t)xfs_fstrm_free_func);
but that cast is causing problems...
  typedef void (*xfs_mru_cache_free_func_t)(unsigned long, void*);
but:
  void xfs_fstrm_free_func( xfs_ino_t ino, fstrm_item_t *item)
so on a 32-bit box, it's casting (32, 32) args into (64, 32) and I assume
it's getting garbage for *item, which subsequently causes an explosion.
With this change the filestreams xfsqa tests don't oops on my 32-bit box.

A couple of fixes for potential fs corruption.

[XFS] On-demand reaping of the MRU cache

Instead of running the mru cache reaper all the time based on a timeout,
we should only run it when the cache has active objects. This allows CPUs
to sleep when there is no activity rather than be woken repeatedly just to
check if there is anything to do.
