[PATCH] md: make sure md/bitmap doesn't try to write a page with active writeback
Due to the use of write-behind, it is possible for md to write a page to the bitmap file that is still completing writeback. This is not allowed. With this patch, we detect those cases and either force a sync write, or back off and try later, as appropriate.
