[XFS] Make xfs_bulkstat() to report unlinked but referenced inodes
We need xfs_bulkstat() to report inode stat for inodes with link count
zero but reference count non zero.
The fix here:
http://oss.sgi.com/archives/xfs/2007-09/msg00266.html
changed this behavior and made xfs_bulkstat() to filter all unlinked
inodes including those that are not destroyed yet but held by reference.
The attached patch returns back to the original behavior by marking the
on-disk inode buffer "dirty" when di_mode is cleared (at that time both
inode link and reference counter are zero).
