hpfs: remove unnecessary dentry_unhash on rmdir, dir rename

2011-05-28T05:02:54+00:00

Hpfs has no problems with references to unlinked directories.

We leave one dentry_unhash call in place, in hpfs_unlink's strange path
where it tries to truncate a file because the disk is full.  I'm not sure
what the full story is there.

vfs: push dentry_unhash on rename_dir into file systems

2011-05-26T11:26:48+00:00

Only a few file systems need this.  Start by pushing it down into each
rename method (except gfs2 and xfs) so that it can be dealt with on a
per-fs basis.

vfs: push dentry_unhash on rmdir into file systems

2011-05-26T11:26:47+00:00

Only a few file systems need this.  Start by pushing it down into each
fs rmdir method (except gfs2 and xfs) so it can be dealt with on a per-fs
basis.

This does not change behavior for any in-tree file systems.

vfs: remove dget() from dentry_unhash()

2011-05-26T11:26:46+00:00

This serves no useful purpose that I can discern.  All callers (rename,
rmdir) hold their own reference to the dentry.

A quick audit of all file systems showed no relevant checks on the value
of d_count in vfs_rmdir/vfs_rename_dir paths.
