Hi,
I've revived my patches to implement livelock avoidance for data integrity
writes. 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.

PS: I'm sorry for sending this twice. I've screwed up the list address in the
