    GFS2: Eliminate sd_rindex_mutex · 6aad1c3d

    Over time, we've slowly eliminated the use of sd_rindex_mutex.
    Up to this point, it was only used in two places: function
    gfs2_ri_total (which totals the file system size by reading
    and parsing the rindex file) and function gfs2_rindex_update
    which updates the rgrps in memory. Both of these functions have
    the rindex glock to protect them, so the rindex is unnecessary.
    Since gfs2_grow writes to the rindex via the meta_fs, the mutex
    is in the wrong order according to the normal rules. This patch
    eliminates the mutex entirely to avoid the problem.
