    Subject[GIT PULL] reiserfs fixes

    Please pull the reiserfs/kill-bkl branch that can be found at:


    These changes fix a lot of lock inversions, some of them were
    triggering soft lockups very easily in xattrs operations.

    As the reiserfs lock is a giant lock (in reiserfs scope),
    these dependency inversions couldn't get smart fixes without a deep
    locking rewrite.

    That's why you'll mostly find dependency inversion fixes based on
    such pattern:


    This is not beautiful but at least that's better than the bkl.

    Oh and I expect other lock inversions will get reported in
    the future due to rare and then yet untested paths.
