      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.
