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? Honza -- To unsubscribe, send a message with 'unsubscribe linux-mm' in the body to majordomo@xxxxxxxxx. For more info on Linux MM, see: http://www.linux-mm.org/ .
