OK, I'll queue revert-revert-mm-remove-__gfp_no_kswapd.patch and the patch from https://patchwork.kernel.org/patch/1728081/. So what I'm currently sitting on for 3.7 is mm-compaction-fix-return-value-of-capture_free_page.patch mm-vmemmap-fix-wrong-use-of-virt_to_page.patch mm-vmscan-fix-endless-loop-in-kswapd-balancing.patch revert-revert-mm-remove-__gfp_no_kswapd.patch mm-avoid-waking-kswapd-for-thp-allocations-when-compaction-is-deferred-or-contended.patch mm-soft-offline-split-thp-at-the-beginning-of-soft_offline_page.patch > > Please identify "Johannes' patch"? > > mm: vmscan: fix kswapd endless loop on higher order allocation OK, we have that. I'll start a round of testing, do another -next drop and send the above Linuswards tomorrow. -- To unsubscribe, send a message with 'unsubscribe linux-mm' in the body to majordomo@xxxxxxxxx.
