There are two changes in this update, which I hope to now be considered for -mm inclusion and pushed for 2.6.36: - reordered the patches to more accurately seperate fixes from enhancements: the order is now very close to how KAMEZAWA Hiroyuki suggested (thanks!), and - the changelog for "oom: badness heuristic rewrite" was slightly expanded to mention how this rewrite improves the oom killer's behavior on the desktop. Many thanks to Nick Piggin for converting the remaining architectures that weren't using the oom killer to handle pagefault oom conditions to do so. His patches have hit mainline, so there is no longer an inconsistency in the semantics of panic_on_oom in such cases! Many thanks to KAMEZAWA Hiroyuki for his help and patience in working with me on this patchset. --- Documentation/feature-removal-schedule.txt | 25 + Documentation/filesystems/proc.txt | 100 ++-- Documentation/sysctl/vm.txt | 23 fs/proc/base.c | 107 ++++ include/linux/memcontrol.h | 8 include/linux/mempolicy.h | 13 include/linux/oom.h | 27 + include/linux/sched.h | 3 kernel/fork.c | 1 kernel/sysctl.c | 12 mm/memcontrol.c | 18 mm/mempolicy.c | 44 + mm/oom_kill.c | 675 ++++++++++++++++------------- mm/page_alloc.c | 29 - 14 files changed, 727 insertions(+), 358 deletions(-) -- To unsubscribe, send a message with 'unsubscribe linux-mm' in the body to majordomo@kvack.org.
