[dm-devel] [PATCH] Device-mapper misc cleanup



This is small patchset for some cleanups I've found during
debugging other issues:

- Zero out bi_end_io: I always find it more convenient to
  explictly zero out things we've set previously. No harm
  done, but possibly easier debugging.
- Simplify call to free_devices(): free_devices() already
  does a list_for_each(), so we don't have to check for
  list_empty...
- Delayed cleanup for dm_table_destroy(): We have krefs
  in the kernel, which does exactly what we want. And I
  fail to see why we can't use them here. Plus we're
  saving an msleep ...

  dm: zero out bi_end_io on remapping failure
  dm-table: simplify call to free_devices()
  dm-table: delayed cleanup for dm_table_destroy()
