TAKE 972004 - Make xfs_bulkstat() to report unlinked but referenced inodes

[Vlad Apostolov <vapo@xxxxxxx>]

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:


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).
