[-- 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.
