Subject: [Cluster-devel] [GFS2 PATCH 02/15] GFS2: Allow fail_gunlock3 to set the free_vfs_inode bit
Date: Mon,  5 Oct 2015 10:36:24 -0500	[thread overview]
Message-ID: <1444059397-4705-3-git-send-email-rpeterso@redhat.com> (raw)
In-Reply-To: <1444059397-4705-1-git-send-email-rpeterso@redhat.com>

This patch changes a failure case in function gfs2_create_inode.
In some error paths, it jumps to label fail_gunlock3, which fails
to set the free_vfs_inode flag. This, in turn, prevents the code
from setting the GIF_FREE_VFS_INODE inode flag. That, in turn,
allow the code to mistakenly unlink the dinode and not ever delete
its data blocks.
