The following should fix it:

Just FYI if anyone tries to run the patch it will not work:

# patch -p1 < ../xfs.patch patching file fs/xfs/xfs_bmap.c
patch: **** malformed patch at line 11: }

So just goto line ~6086 and add the kmem_free(out); above the return error.

Status:
This patch fixes the problem, thanks!

Justin.
