[Mark Tinguely <tinguely@sgi.com>]

[-- Attachment #1: xfstests-v2-fill-directory.patch --]
[-- Type: text/plain, Size: 3199 bytes --]

This tests triggers an assert in the XFS directory unbalance code.
This test originally written by Brian Foster and suggestions
from Micheal Semon.

Signed-off-by: Mark Tinguely <tinguely@sgi.com> 
---
v1->v2:
 remove clean up.
 remove $seqres.full before test.
 remove scratch mount.
 11g -> calculate 11g bytes.
 check for failing mkfs and mount.
 add a safer removal of the scratch files.

 put into auto group and "long" group so people can opt out:
  this test almost an hour on my test box.
