[Cluster-devel] [PATCH 02/11] GFS2: Allow fail_gunlock3 to set the free_vfs_inode bit

[Bob Peterson <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.
