      VFS: Add forget_all_cached_acls() · 796bd952
      Steven Whitehouse authored 
      This is required for cluster filesystems which want to use
cached ACLs so that they can invalidate the cache when
required.

      GFS2: Fix up system xattrs · 2646a1f6
      Steven Whitehouse authored 
      This code has been shamelessly stolen from XFS at the suggestion
of Christoph Hellwig. I've not added support for cached ACLs so
far... watch for that in a later patch, although this is designed
in such a way that they should be easy to add.

      GFS2: Fix -o meta mounts for subsequent mounts (i.e. all but the first one) · f55073ff
      Steven Whitehouse authored 
      We have a long term plan to use the "-o meta" flag to GFS2 mounts to
access the alternate root which is used to store metadata for a GFS2
filesystem. This will allow us to eventually remove support for the
gfs2meta filesystem type (which is in any case just a "front end" to
the gfs2 filesystem type with the meta/master root).

Currently the "-o meta" option is only taken into account on the
initial mount of the filesystem. Subsequent mounts of the same
filesystem (i.e. on the same device) result in basically the same
as bind mounting the root of the original mount.

This patch changes that by using what is more or less a copy
of get_sb_bdev() and extending it so that it will take into
account the alternate root in all cases. The main difference
is that we have to parse the mount options a bit earlier. We can
then use them to select the appropriate root towards the end of
the function.

In addition this also fixes a bug where it was possible (but certainly
not desirable) to set different ro/rw options for the meta root
when mounted via the gfs2meta fs compared with the original mount.

      GFS2: Fix potential race in glock code · 7e71c55e
      Steven Whitehouse authored 
      We need to be careful of the ordering between clearing the
GLF_LOCK bit and scheduling the workqueue.
