Some relatively minor changes for gfs2:

Browse Source 
- An initial batch of obvious cleanups and fixes from Bob's
    recovery patch queue.
  - Two iomap conversion patches and some cleanups from Christoph
    Hellwig.
  - A cosmetic cleanup from Kefeng Wang (Huawei).
  - Another minor fix and cleanup by me.
