There was some unfortunate crossover in timing as I see mmotm has pulled
in the previous follow up series. It would probably be easiest to replace
these patches

mm-vmscan-stall-page-reclaim-and-writeback-pages-based-on-dirty-writepage-pages-encountered.patch
mm-vmscan-stall-page-reclaim-after-a-list-of-pages-have-been-processed.patch
mm-vmscan-take-page-buffers-dirty-and-locked-state-into-account.patch
mm-vmscan-stall-page-reclaim-and-writeback-pages-based-on-dirty-writepage-pages-encountered.patch

with patches 2-8 of this series. The fixup patch
mm-vmscan-block-kswapd-if-it-is-encountering-pages-under-writeback-fix-2.patch
is still the same

Sorry for the inconvenience.
