Due to some concerns whether tagging of pages before writeout cannot be too costly to use for WB_SYNC_NONE mode (where we stop after nr_to_write pages) I've changed the patch to use page tagging only in WB_SYNC_ALL mode where we are sure that we write out all the tagged pages. Later, we can think about using tagging for livelock avoidance for WB_SYNC_NONE mode as well... As always comments are welcome.
