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.
