      "message": "oom-kill: fix NUMA constraint check with nodemask\n\nFix node-oriented allocation handling in oom-kill.c I myself think of this\nas a bugfix not as an ehnancement.\n\nIn these days, things are changed as\n  - alloc_pages() eats nodemask as its arguments, __alloc_pages_nodemask().\n  - mempolicy don\u0027t maintain its own private zonelists.\n  (And cpuset doesn\u0027t use nodemask for __alloc_pages_nodemask())\n\nSo, current oom-killer\u0027s check function is wrong.\n\nThis patch does\n  - check nodemask, if nodemask \u0026\u0026 nodemask doesn\u0027t cover all\n    node_states[N_HIGH_MEMORY], this is CONSTRAINT_MEMORY_POLICY.\n  - Scan all zonelist under nodemask, if it hits cpuset\u0027s wall\n    this faiulre is from cpuset.\nAnd\n  - modifies the caller of out_of_memory not to call oom if __GFP_THISNODE.\n    This doesn\u0027t change \"current\" behavior. If callers use __GFP_THISNODE\n    it should handle \"page allocation failure\" by itself.\n\n  - handle __GFP_NOFAIL+__GFP_THISNODE path.\n    This is something like a FIXME but this gfpmask is not used now.\n\n[akpm@linux-foundation.org: coding-style fixes]\nSigned-off-by: KAMEZAWA Hiroyuki \u003ckamezawa.hioryu@jp.fujitsu.com\u003e\nAcked-by: David Rientjes \u003crientjes@google.com\u003e\nCc: Daisuke Nishimura \u003cnishimura@mxp.nes.nec.co.jp\u003e\nCc: KOSAKI Motohiro \u003ckosaki.motohiro@jp.fujitsu.com\u003e\nCc: Christoph Lameter \u003ccl@linux-foundation.org\u003e\nSigned-off-by: Andrew Morton \u003cakpm@linux-foundation.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@linux-foundation.org\u003e\n"

      "message": "mm: have zonelist contains structs with both a zone pointer and zone_idx\n\nFiltering zonelists requires very frequent use of zone_idx().  This is costly\nas it involves a lookup of another structure and a substraction operation.  As\nthe zone_idx is often required, it should be quickly accessible.  The node idx\ncould also be stored here if it was found that accessing zone-\u003enode is\nsignificant which may be the case on workloads where nodemasks are heavily\nused.\n\nThis patch introduces a struct zoneref to store a zone pointer and a zone\nindex.  The zonelist then consists of an array of these struct zonerefs which\nare looked up as necessary.  Helpers are given for accessing the zone index as\nwell as the node index.\n\n[kamezawa.hiroyu@jp.fujitsu.com: Suggested struct zoneref instead of embedding information in pointers]\n[hugh@veritas.com: mm-have-zonelist: fix memcg ooms]\n[hugh@veritas.com: just return do_try_to_free_pages]\n[hugh@veritas.com: do_try_to_free_pages gfp_mask redundant]\nSigned-off-by: Mel Gorman \u003cmel@csn.ul.ie\u003e\nAcked-by: Christoph Lameter \u003cclameter@sgi.com\u003e\nAcked-by: David Rientjes \u003crientjes@google.com\u003e\nSigned-off-by: Lee Schermerhorn \u003clee.schermerhorn@hp.com\u003e\nCc: KAMEZAWA Hiroyuki \u003ckamezawa.hiroyu@jp.fujitsu.com\u003e\nCc: Mel Gorman \u003cmel@csn.ul.ie\u003e\nCc: Christoph Lameter \u003cclameter@sgi.com\u003e\nCc: Nick Piggin \u003cnickpiggin@yahoo.com.au\u003e\nSigned-off-by: Hugh Dickins \u003chugh@veritas.com\u003e\nSigned-off-by: Andrew Morton \u003cakpm@linux-foundation.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@linux-foundation.org\u003e\n"
