Subject: [PATCH 0/4] Get rid of iput() from flusher thread

  Hi,

  this patch set changes writeback_sb_inodes() to avoid iput() which might
be problematic (see patch 4 which tries to summarize our email discussions)
for some filesystems.

  Patches 1 and 2 are trivial mostly unrelated fixes (Fengguang, can you can
take these and merge them right away please?). Patch 3 is a preparatory code
reshuffle and patch 4 removes the __iget() / iput() from flusher thread.

  As a side note, your patches to offload writeback from kswapd to flusher
thread then won't need iget/iput either if we pass page references as we talked
so that should resolve most of the concerns.

  What do you think guys?
