Here's a KSM series, based on mmotm 2013-01-23-17-04: starting with Petr's v7 "KSM: numa awareness sysfs knob"; then fixing the two issues we had with that, fully enabling KSM page migration on the way. (A different kind of KSM/NUMA issue which I've certainly not begun to address here: when KSM pages are unmerged, there's usually no sense in preferring to allocate the new pages local to the caller's node.) Petr, I have intentionally changed the titles of yours: partly because your "sysfs knob" understated it, but mainly because I think gmail is liable to assign 1/11 and 2/11 to your earlier December thread, making them vanish from this series. I hope a change of title prevents that. 1 ksm: allow trees per NUMA node 2 ksm: add sysfs ABI Documentation 3 ksm: trivial tidyups 4 ksm: reorganize ksm_check_stable_tree 5 ksm: get_ksm_page locked 6 ksm: remove old stable nodes more thoroughly 7 ksm: make KSM page migration possible 8 ksm: make !merge_across_nodes migration safe 9 mm: enable KSM page migration 10 mm: remove offlining arg to migrate_pages 11 ksm: stop hotremove lockdep warning Documentation/ABI/testing/sysfs-kernel-mm-ksm | 52 + Documentation/vm/ksm.txt | 7 include/linux/ksm.h | 18 include/linux/migrate.h | 14 mm/compaction.c | 2 mm/ksm.c | 566 +++++++++++++--- mm/memory-failure.c | 7 mm/memory.c | 19 mm/memory_hotplug.c | 3 mm/mempolicy.c | 11 mm/migrate.c | 61 - mm/page_alloc.c | 6 12 files changed, 580 insertions(+), 186 deletions(-) Hugh -- To unsubscribe, send a message with 'unsubscribe linux-mm' in the body to majordomo@xxxxxxxxx.
