[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).
