Subject: [PATCH] GFS2: bz 222302: gfs2 knows of directories which it chooses  not to display
Date: Fri, 26 Jan 2007 09:12:54 -0600
Bugzilla: 222302
Message-Id: <45BA1A76.3070905@redhat.com>
Changelog: [gfs2] corrrectly display revalidated directories


This patch is for bugzilla bug bz #222302:

Moving a virtual IP from node to node between two NFS-over-GFS2
servers was causing one of the GFS2 servers to become confused and
reference a deleted inode.  The problem was due to vfs dentries that did
not reference the gfs2_dops and therefore didn't call the gfs2 revalidate
code to revalidate a dentry after a file or directory had been deleted &
recreated.  This patch is a crosswrite from a RHEL4 bug found in
GFS1 as bz #190756 and it is against kernel-2.6.18-6.el5.
This patch is in the latest -nmw branch of Steve Whitehouse's upstream
git tree.
