[PATCH] xfstests: generic/313, test sgid inheritance on subdirs

To: xfs-oss <xfs@xxxxxxxxxxx>
Subject: [PATCH] xfstests: generic/313, test sgid inheritance on subdirs
From: Eric Sandeen <sandeen@xxxxxxxxxx>
Date: Wed, 29 May 2013 17:30:13 -0500
Delivered-to: xfs@xxxxxxxxxxx
User-agent: Mozilla/5.0 (Macintosh; Intel Mac OS X 10.8; rv:17.0) Gecko/20130509 Thunderbird/17.0.6
On XFS this test fails today due to some over-eager
SGID removal in xfs core code; ext4 & btrfs pass.
Document it in a test, will send xfs patch in a bit.

Signed-off-by: Eric Sandeen <sandeen@xxxxxxxxxx>

p.s.  I'm going to just flaunt my ignorance and say:
I've never understood acls well.  I'm hoping someone who does
can help me write a better changelog, because this one
is no good at all!
