      "message": "cpuset,mm: fix no node to alloc memory when changing cpuset\u0027s mems\n\nBefore applying this patch, cpuset updates task-\u003emems_allowed and\nmempolicy by setting all new bits in the nodemask first, and clearing all\nold unallowed bits later.  But in the way, the allocator may find that\nthere is no node to alloc memory.\n\nThe reason is that cpuset rebinds the task\u0027s mempolicy, it cleans the\nnodes which the allocater can alloc pages on, for example:\n\n(mpol: mempolicy)\n\ttask1\t\t\ttask1\u0027s mpol\ttask2\n\talloc page\t\t1\n\t  alloc on node0? NO\t1\n\t\t\t\t1\t\tchange mems from 1 to 0\n\t\t\t\t1\t\trebind task1\u0027s mpol\n\t\t\t\t0-1\t\t  set new bits\n\t\t\t\t0\t  \t  clear disallowed bits\n\t  alloc on node1? NO\t0\n\t  ...\n\tcan\u0027t alloc page\n\t  goto oom\n\nThis patch fixes this problem by expanding the nodes range first(set newly\nallowed bits) and shrink it lazily(clear newly disallowed bits).  So we\nuse a variable to tell the write-side task that read-side task is reading\nnodemask, and the write-side task clears newly disallowed nodes after\nread-side task ends the current memory allocation.\n\n[akpm@linux-foundation.org: fix spello]\nSigned-off-by: Miao Xie \u003cmiaox@cn.fujitsu.com\u003e\nCc: David Rientjes \u003crientjes@google.com\u003e\nCc: Nick Piggin \u003cnpiggin@suse.de\u003e\nCc: Paul Menage \u003cmenage@google.com\u003e\nCc: Lee Schermerhorn \u003clee.schermerhorn@hp.com\u003e\nCc: Hugh Dickins \u003chugh.dickins@tiscali.co.uk\u003e\nCc: Ravikiran Thirumalai \u003ckiran@scalex86.org\u003e\nCc: KOSAKI Motohiro \u003ckosaki.motohiro@jp.fujitsu.com\u003e\nCc: Christoph Lameter \u003ccl@linux-foundation.org\u003e\nCc: Andi Kleen \u003candi@firstfloor.org\u003e\nSigned-off-by: Andrew Morton \u003cakpm@linux-foundation.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@linux-foundation.org\u003e\n"

The\nmost notable example is for objects that are PAGE_SIZE bytes in size.\n\nHigher minimum slab orders may cause page allocation failures when oom or\nunder heavy fragmentation.\n\nThis patch adds a new slub_debug option, which disables debugging by\ndefault for caches that would have resulted in higher minimum orders:\n\n\tslub_debug\u003dO\n\nWhen this option is used on systems with 4K pages, kmalloc-4096, for\nexample, will not have debugging enabled by default even if\nCONFIG_SLUB_DEBUG_ON is defined because it would have resulted in a\norder-1 minimum slab order.\n\nReported-by: Larry Finger \u003cLarry.Finger@lwfinger.net\u003e\nTested-by: Larry Finger \u003cLarry.Finger@lwfinger.net\u003e\nCc: Christoph Lameter \u003ccl@linux-foundation.org\u003e\nSigned-off-by: David Rientjes \u003crientjes@google.com\u003e\nSigned-off-by: Pekka Enberg \u003cpenberg@cs.helsinki.fi\u003e\n"

      "message": "slub: add min_partial sysfs tunable\n\nNow that a cache\u0027s min_partial has been moved to struct kmem_cache, it\u0027s\npossible to easily tune it from userspace by adding a sysfs attribute.\n\nIt may not be desirable to keep a large number of partial slabs around\nif a cache is used infrequently and memory, especially when constrained\nby a cgroup, is scarce.  It\u0027s better to allow userspace to set the\nminimum policy per cache instead of relying explicitly on\nkmem_cache_shrink().\n\nThe memory savings from simply moving min_partial from struct\nkmem_cache_node to struct kmem_cache is obviously not significant\n(unless maybe you\u0027re from SGI or something), at the largest it\u0027s\n\n\t# allocated caches * (MAX_NUMNODES - 1) * sizeof(unsigned long)\n\nThe true savings occurs when userspace reduces the number of partial\nslabs that would otherwise be wasted, especially on machines with a\nlarge number of nodes (ia64 with CONFIG_NODES_SHIFT at 10 for default?).\nAs well as the kernel estimates ideal values for n-\u003emin_partial and\nensures it\u0027s within a sane range, userspace has no other input other\nthan writing to /sys/kernel/slab/cache/shrink.\n\nThere simply isn\u0027t any better heuristic to add when calculating the\npartial values for a better estimate that works for all possible caches.\nAnd since it\u0027s currently a static value, the user really has no way of\nreclaiming that wasted space, which can be significant when constrained\nby a cgroup (either cpusets or, later, memory controller slab limits)\nwithout shrinking it entirely.\n\nThis also allows the user to specify that increased fragmentation and\nmore partial slabs are actually desired to avoid the cost of allocating\nnew slabs at runtime for specific caches.\n\nThere\u0027s also no reason why this should be a per-struct kmem_cache_node\nvalue in the first place.  You could argue that a machine would have\nsuch node size asymmetries that it should be specified on a per-node\nbasis, but we know nobody is doing that right now since it\u0027s a purely\nstatic value at the moment and there\u0027s no convenient way to tune that\nvia slub\u0027s sysfs interface.\n\nCc: Christoph Lameter \u003ccl@linux-foundation.org\u003e\nSigned-off-by: David Rientjes \u003crientjes@google.com\u003e\nSigned-off-by: Pekka Enberg \u003cpenberg@cs.helsinki.fi\u003e\n"

I don\u0027t know why but that shouldn\u0027t\nbe difficult to find.\n\nI moved linux/tracepoint.h to trace/tracepoint.h as well. I think that would\nbe more easy to find the tracer headers if they are all in their common\ndirectory.\n\nSigned-off-by: Frederic Weisbecker \u003cfweisbec@gmail.com\u003e\nSigned-off-by: Ingo Molnar \u003cmingo@elte.hu\u003e\n"
