Hi,

vserver patch introduces a bug in xfs handling in 3.2 kernels. It causes hangs 
like http://oss.sgi.com/pipermail/xfs/2012-March/017685.html

Here is info on how to fix it:

In the 3.2 version xfs sync flags does a double unlock of the ilock -
change the last argument of xfs trans ijoin from XFS ILOCK EXCL to 0
will fix this.  The 3.0 version doesn't have this bug.

And btw, the additions to the on-disk format are gross - this stuff
broke before and will break again when we add new features.
