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. -- Mel Gorman SUSE Labs -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
