This patchset is a rewrite of the out of memory killer to address several issues that have been raised recently. The most notable change is a complete rewrite of the badness heuristic that determines which task is killed; the goal was to make it as simple and predictable as possible while still addressing issues that plague the VM. This patchset is based on mmotm-2010-02-05-15-06 because of the following dependencies: [patch 4/7] oom: badness heuristic rewrite: mm-count-swap-usage.patch [patch 5/7] oom: replace sysctls with quick mode: sysctl-clean-up-vm-related-variable-delcarations.patch To apply to mainline, download 2.6.33-rc7 and apply mm-clean-up-mm_counter.patch mm-avoid-false-sharing-of-mm_counter.patch mm-avoid-false_sharing-of-mm_counter-checkpatch-fixes.patch mm-count-swap-usage.patch mm-count-swap-usage-checkpatch-fixes.patch mm-introduce-dump_page-and-print-symbolic-flag-names.patch sysctl-clean-up-vm-related-variable-declarations.patch sysctl-clean-up-vm-related-variable-declarations-fix.patch from http://userweb.kernel.org/~akpm/mmotm/broken-out.tar.gz first. --- Documentation/filesystems/proc.txt | 78 ++++--- Documentation/sysctl/vm.txt | 51 ++--- fs/proc/base.c | 13 +- include/linux/mempolicy.h | 13 +- include/linux/oom.h | 18 +- kernel/sysctl.c | 15 +- mm/mempolicy.c | 39 +++ mm/oom_kill.c | 455 +++++++++++++++++++----------------- mm/page_alloc.c | 3 + 9 files changed, 383 insertions(+), 302 deletions(-) -- To unsubscribe, send a message with 'unsubscribe linux-mm' in the body to majordomo@xxxxxxxxxx For more info on Linux MM, see: http://www.linux-mm.org/ .
