But this has some troubles. Usually when a set of threads works in\na cooperative way, they tend to operate on the same node. So if they hit\nlimits under memcg they will reclaim memory from themselves, damaging the\nactive working set.\n\nFor example, assume 2 node system which has Node 0 and Node 1 and a memcg\nwhich has 1G limit. After some work, file cache remains and the usages\nare\n\n Node 0: 1M\n Node 1: 998M.\n\nand run an application on Node 0, it will eat its foot before freeing\nunnecessary file caches.\n\nThis patch adds round-robin for NUMA and adds equal pressure to each node.\nWhen using cpuset\u0027s spread memory feature, this will work very well.\n\nBut yes, a better algorithm is needed.\n\n[akpm@linux-foundation.org: comment editing]\n[kamezawa.hiroyu@jp.fujitsu.com: fix time comparisons]\nSigned-off-by: Ying Han \u003cyinghan@google.com\u003e\nSigned-off-by: KAMEZAWA Hiroyuki \u003ckamezawa.hiroyu@jp.fujitsu.com\u003e\nCc: Balbir Singh \u003cbalbir@in.ibm.com\u003e\nCc: KOSAKI Motohiro \u003ckosaki.motohiro@jp.fujitsu.com\u003e\nCc: Daisuke Nishimura \u003cnishimura@mxp.nes.nec.co.jp\u003e\nCc: Mel Gorman \u003cmel@csn.ul.ie\u003e\nSigned-off-by: Andrew Morton \u003cakpm@linux-foundation.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@linux-foundation.org\u003e\n" }, { "commit": "0ae5e89c60c9eb87da36a2614836bc434b0ec2ad", "tree": "0d509fd83ac7e7d2f52dfcbba769c43aeeb68b5f", "parents": [ "f042e707ee671e4beb5389abeb9a1819a2cf5532" ], "author": { "name": "Ying Han", "email": "yinghan@google.com", "time": "Thu May 26 16:25:25 2011 -0700" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@linux-foundation.org", "time": "Thu May 26 17:12:35 2011 -0700" }, "message": "memcg: count the soft_limit reclaim in global background reclaim\n\nThe global kswapd scans per-zone LRU and reclaims pages regardless of the\ncgroup.

If a filesystem does not implement any\n{get,set,list}xattr functions the VFS will call into some random LSM hooks\nand the running LSM can then implement some method for handling xattrs.\nSELinux for example provides a method to support security.selinux but no\nother security.* xattrs.\n\nAs it stands today when one enables CONFIG_TMPFS_POSIX_ACL tmpfs will have\nxattr handler routines specifically to handle acls. Because of this tmpfs\nwould loose the VFS/LSM helpers to support the running LSM. To make up\nfor that tmpfs had stub functions that did nothing but call into the LSM\nhooks which implement the helpers.\n\nThis new patch does not use the LSM fallback functions and instead just\nimplements a native get/set/list xattr feature for the full security.* and\ntrusted.* namespace like a normal filesystem. This means that tmpfs can\nnow support both security.selinux and security.capability, which was not\npreviously possible.\n\nThe basic implementation is that I attach a:\n\nstruct shmem_xattr {\n\tstruct list_head list; /* anchored by shmem_inode_info-\u003exattr_list */\n\tchar *name;\n\tsize_t size;\n\tchar value[0];\n};\n\nInto the struct shmem_inode_info for each xattr that is set. This\nimplementation could easily support the user.* namespace as well, except\nsome care needs to be taken to prevent large amounts of unswappable memory\nbeing allocated for unprivileged users.\n\n[mszeredi@suse.cz: new config option, suport trusted.*, support symlinks]\nSigned-off-by: Eric Paris \u003ceparis@redhat.com\u003e\nSigned-off-by: Miklos Szeredi \u003cmszeredi@suse.cz\u003e\nAcked-by: Serge Hallyn \u003cserge.hallyn@ubuntu.com\u003e\nTested-by: Serge Hallyn \u003cserge.hallyn@ubuntu.com\u003e\nCc: Kyle McMartin \u003ckyle@mcmartin.ca\u003e\nAcked-by: Hugh Dickins \u003chughd@google.com\u003e\nTested-by: Jordi Pujol \u003cjordipujolp@gmail.com\u003e\nSigned-off-by: Andrew Morton \u003cakpm@linux-foundation.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@linux-foundation.org\u003e\n" }, { "commit": "8bba154ef29e16331e578029e9050c74b87b7ff9", "tree": "9dc8ecea8b09d82f72de2dfae367c3a6086e3eb1", "parents": [ "172703b08cd05e2d5196ac13e94cc186f629d58b" ], "author": { "name": "Yinghai Lu", "email": "yinghai@kernel.org", "time": "Tue May 24 17:12:37 2011 -0700" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@linux-foundation.org", "time": "Wed May 25 08:39:30 2011 -0700" }, "message": "memblock/nobootmem: allow alloc_bootmem() to take 0 as low limit\n\nThe bootmem wrapper with memblock supports top-down now, so we do not need\nto set the low limit to __pa(MAX_DMA_ADDRESS).\n\nThe logic should be: good to allocate above __pa(MAX_DMA_ADDRESS), but it\nis ok if we can not find memory above 16M on system that has a small\namount of RAM.\n\nSigned-off-by: Yinghai LU \u003cyinghai@kernel.org\u003e\nCc: Ingo Molnar \u003cmingo@elte.hu\u003e\nCc: \"H.

For example, when adding new\ncallers of the *_mm_counter() functions a developer needs to ensure that\nthose paths are always executed with page_table_lock held, in case we\u0027re\nusing the non-atomic implementation of mm counters.\n\nHugh Dickins introduced the atomic mm counters in commit f412ac08c986\n(\"[PATCH] mm: fix rss and mmlist locking\"). When asked why he left the\nnon-atomic counters around he said,\n\n | The only reason was to avoid adding costly atomic operations into a\n | configuration that had no need for them there: the page_table_lock\n | sufficed.\n |\n | Certainly it would be simpler just to delete the non-atomic variant.\n |\n | And I think it\u0027s fair to say that any configuration on which we\u0027re\n | measuring performance to that degree (rather than \"does it boot fast?\"\n | type measurements), would already be going the split ptlocks route.\n\nRemoving the non-atomic counters eases the maintenance burden because\ndevelopers no longer have to mindful of the two implementations when using\n*_mm_counter().\n\nNote that all architectures provide a means of atomically updating\natomic_long_t variables, even if they have to revert to the generic\nspinlock implementation because they don\u0027t support 64-bit atomic\ninstructions (see lib/atomic64.c).\n\nSigned-off-by: Matt Fleming \u003cmatt.fleming@linux.intel.com\u003e\nAcked-by: Dave Hansen \u003cdave@linux.vnet.ibm.com\u003e\nAcked-by: KAMEZAWA Hiroyuki \u003ckamezawa.hiroyu@jp.fujitsu.com\u003e\nCc: Hugh Dickins \u003chughd@google.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" }, { "commit": "ba93fa81b5f2bf0076407a3a777fff122ce16220", "tree": "c859d60816b3815679b45d7e492fbbe03e7e2b19", "parents": [ "e3c40f379a144f35e53864a2cd970e238071afd7" ], "author": { "name": "Daniel Kiper", "email": "dkiper@net-space.pl", "time": "Tue May 24 17:12:34 2011 -0700" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@linux-foundation.org", "time": "Wed May 25 08:39:29 2011 -0700" }, "message": "mm: do not define PFN_SECTION_SHIFT if !CONFIG_SPARSEMEM\n\nDo not define PFN_SECTION_SHIFT if !CONFIG_SPARSEMEM.\n\nSigned-off-by: Daniel Kiper \u003cdkiper@net-space.pl\u003e\nAcked-by: Dave Hansen \u003cdave@linux.vnet.ibm.com\u003e\nSigned-off-by: Andrew Morton \u003cakpm@linux-foundation.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@linux-foundation.org\u003e\n" }, { "commit": "e3c40f379a144f35e53864a2cd970e238071afd7", "tree": "6636214fe729d2ee08780a44ab92bed66c0074db", "parents": [ "bf4e8902ee5080f5d2c810b639e7e778c8082b52" ], "author": { "name": "Daniel Kiper", "email": "dkiper@net-space.pl", "time": "Tue May 24 17:12:33 2011 -0700" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@linux-foundation.org", "time": "Wed May 25 08:39:29 2011 -0700" }, "message": "mm: pfn_to_section_nr()/section_nr_to_pfn() is valid only in CONFIG_SPARSEMEM context\n\npfn_to_section_nr()/section_nr_to_pfn() is valid only in CONFIG_SPARSEMEM\ncontext.

For review\npurpose I\u0027ve split them into generic and per-arch patches with the last of\nthose a generic cleanup.\n\nThe next patch provides generic RCU page-table freeing, and the followup\nis a patch converting s390 to use this. I\u0027ve also got 4 patches from\nDaveM lined up (not included in this series) that uses this to implement\ngup_fast() for sparc64.\n\nThen there is one patch that extends the generic mmu_gather batching.\n\nAfter that follow the mm preemptibility patches, these make part of the mm\na lot more preemptible. It converts i_mmap_lock and anon_vma-\u003elock to\nmutexes which together with the mmu_gather rework makes mmu_gather\npreemptible as well.\n\nMaking i_mmap_lock a mutex also enables a clean-up of the truncate code.\n\nThis also allows for preemptible mmu_notifiers, something that XPMEM I\nthink wants.\n\nFurthermore, it removes the new and universially detested unmap_mutex.\n\nThis patch:\n\nRemove the first obstacle towards a fully preemptible mmu_gather.\n\nThe current scheme assumes mmu_gather is always done with preemption\ndisabled and uses per-cpu storage for the page batches. Change this to\ntry and allocate a page for batching and in case of failure, use a small\non-stack array to make some progress.\n\nPreemptible mmu_gather is desired in general and usable once i_mmap_lock\nbecomes a mutex. Doing it before the mutex conversion saves us from\nhaving to rework the code by moving the mmu_gather bits inside the\npte_lock.\n\nAlso avoid flushing the tlb batches from under the pte lock, this is\nuseful even without the i_mmap_lock conversion as it significantly reduces\npte lock hold times.\n\n[akpm@linux-foundation.org: fix comment tpyo]\nSigned-off-by: Peter Zijlstra \u003ca.p.zijlstra@chello.nl\u003e\nCc: Benjamin Herrenschmidt \u003cbenh@kernel.crashing.org\u003e\nCc: David Miller \u003cdavem@davemloft.net\u003e\nCc: Martin Schwidefsky \u003cschwidefsky@de.ibm.com\u003e\nCc: Russell King \u003crmk@arm.linux.org.uk\u003e\nCc: Paul Mundt \u003clethal@linux-sh.org\u003e\nCc: Jeff Dike \u003cjdike@addtoit.com\u003e\nCc: Richard Weinberger \u003crichard@nod.at\u003e\nCc: Tony Luck \u003ctony.luck@intel.com\u003e\nReviewed-by: KAMEZAWA Hiroyuki \u003ckamezawa.hiroyu@jp.fujitsu.com\u003e\nAcked-by: Hugh Dickins \u003chughd@google.com\u003e\nAcked-by: Mel Gorman \u003cmel@csn.ul.ie\u003e\nCc: KOSAKI Motohiro \u003ckosaki.motohiro@jp.fujitsu.com\u003e\nCc: Nick Piggin \u003cnpiggin@kernel.dk\u003e\nCc: Namhyung Kim \u003cnamhyung@gmail.com\u003e\nSigned-off-by: Andrew Morton \u003cakpm@linux-foundation.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@linux-foundation.org\u003e\n" }, { "commit": "d05f3169c0fbca16132ec7c2be71685c6de638b5", "tree": "37d82004869fa4e530617883f12cab7538dbd4a6", "parents": [ "248ac0e1943ad1796393d281b096184719eb3f97" ], "author": { "name": "Michal Hocko", "email": "mhocko@suse.cz", "time": "Tue May 24 17:11:44 2011 -0700" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@linux-foundation.org", "time": "Wed May 25 08:39:12 2011 -0700" }, "message": "mm: make expand_downwards() symmetrical with expand_upwards()\n\nCurrently we have expand_upwards exported while expand_downwards is\naccessible only via expand_stack or expand_stack_downwards.\n\ncheck_stack_guard_page is a nice example of the asymmetry.
