The patch "mm: vmscan: Block kswapd if it is encountering pages under
writeback" stalls in congestion_wait it encounters a page under writeback
that is marked for immediate reclaim. Initially this was a
wait_on_page_writeback() but after the switch to congestion_wait(), there
is no guarantee the page has completed writeback and it can be placed on a
list for freeing.
This is a fix for
mm-vmscan-block-kswapd-if-it-is-encountering-pages-under-writeback.patch
