           Summary: With parallel-readdir enabled, deleting a directory
                    containing stale linkto files fails with "Directory

This bug was initially created as a copy of Bug #1672851

I am copying this bug because: 



Description of problem:

If parallel-readdir is enabled on a volume, rm -rf <dir> fails with "Directory
not empty" if <dir> contains stale linkto files.


Version-Release number of selected component (if applicable):


How reproducible:
Consistently

Steps to Reproduce:
1. Create a 3 brick distribute volume
2. Enable parallel-readdir and readdir-ahead on the volume
3. Fuse mount the volume and mkdir dir0
4. Create some files inside dir0 and rename them so linkto files are created on
the bricks
5. Check the bricks to see which files have linkto files. Delete the data files
directly on the bricks, leaving the linkto files behind. These are now stale
linkto files.
6. Remount the volume
7. rm -rf dir0

Actual results:
[root at rhgs313-6 fuse1]# rm -rf dir0/
rm: cannot remove ‘dir0/’: Directory not empty


Expected results:
dir0 should be deleted without errors
