SGI folks,

Looks like Christoph is having problems posting to the list;
the spam filter is dropping all his mail. In the mean time,
here's a fix for an oops in the tracing code as a result of
the last check ins. I didn't see this because the "combine
inodes" patches removes xfs_icount altogether.

Lachlan also saw some regressions after merging these patchsets :
. replace the mount inode list with radix tree traversals
. clean up sync code

If that
series is going to be included in the current round of checkins
then this patch probably isn't needed.

The agreed plan for 2.6.28 still has the following patchsets to go in:

. Combine the XFS and Linux inode structures V2
. Track reclaimable inodes in inode cache
. AIL cleanup and bug fixes
. Account for allocated blocks when expanding directories
. Check for valid transaction headers in recovery
. fix remount rw with unrecognized options

It's starting to look like a pretty aggressive merge and QA schedule.
Dave, is it worth doing any testing until these are *all* merged?
