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? Honza
