These have to be allocated\nin the same AG as we only reserve enough blocks in an allocation\ntransaction for modification of the freespace trees in a single AG.\n\nxfs_alloc_fix_minleft() has been considering blocks on the AGFL as\nfree blocks available for extent and bmbt block allocation, which is\nnot correct - blocks on the AGFL are there exclusively for the use\nof the free space btrees.

This is extremely sub-optimal as we\nhave to mark every transaction with blocks that get reused as synchronous.\n\nInstead of searching the busy extent list after deciding on the extent to\nallocate, check each candidate extent during the allocation decisions as\nto whether they are in the busy list. If they are in the busy list, we\ntrim the busy range out of the extent we have found and determine if that\ntrimmed range is still OK for allocation. In many cases, this check can\nbe incorporated into the allocation extent alignment code which already\ndoes trimming of the found extent before determining if it is a valid\ncandidate for allocation.\n\nBased on earlier patches from Dave Chinner.\n\nSigned-off-by: Christoph Hellwig \u003chch@lst.de\u003e\nSigned-off-by: Alex Elder \u003caelder@sgi.com\u003e\n" }, { "commit": "a870acd9b2671de56514a430edfa7867823c31c9", "tree": "e288e41227c35c251a675e4901f0be35e0c26aa1", "parents": [ "3eff1268994f72266b660782e87f215720c29639" ], "author": { "name": "Christoph Hellwig", "email": "hch@infradead.org", "time": "Sun Apr 24 19:06:14 2011 +0000" }, "committer": { "name": "Alex Elder", "email": "aelder@sgi.com", "time": "Thu Apr 28 13:17:56 2011 -0500" }, "message": "xfs: optimize AGFL refills\n\nWhile we need to make sure we do not reuse busy extents, there is no need\nto force out busy extents when moving them between the AGFL and the\nfreespace btree as we still take care of that when doing the real allocation.\n\nTo avoid the log force when just moving extents from the different free\nspace tracking structures, move the busy search out of\nxfs_alloc_get_freelist into the callers that need it, and move the busy\nlist insert from xfs_free_ag_extent which is used both by AGFL refills\nand real allocation to xfs_free_extent, which is only used by the latter.\n\nSigned-off-by: Christoph Hellwig \u003chch@lst.de\u003e\nSigned-off-by: Alex Elder \u003caelder@sgi.com\u003e\n" }, { "commit": "3eff1268994f72266b660782e87f215720c29639", "tree": "8299f6a1e6c5eefcc8597f232146e11b06aad922", "parents": [ "f0e615c3cb72b42191b558c130409335812621d8" ], "author": { "name": "Dave Chinner", "email": "dchinner@redhat.com", "time": "Tue Apr 12 13:34:20 2011 +0000" }, "committer": { "name": "Alex Elder", "email": "aelder@sgi.com", "time": "Wed Apr 20 11:36:49 2011 -0500" }, "message": "xfs: fix duplicate message output\n\nCommit 957935dc (\"xfs: fix xfs_debug warnings\" broke the logic in\n__xfs_printk().

As\nthe FS fragments, these clusters become harder to find and we have\nto decide between allocating a new chunk to make more clusters\nor giving up on the cluster to allocate from the free space\nwe have.\n\nRight now it creates too many chunks, and you can end up with\na whole FS that is mostly empty metadata chunks. This commit\nchanges the allocation code to be more strict and only\nallocate new chunks when we\u0027ve made good use of the chunks we\nalready have.\n\nSigned-off-by: Chris Mason \u003cchris.mason@oracle.com\u003e\n" }, { "commit": "7d6b46707f2491a94f4bd3b4329d2d7f809e9368", "tree": "e5a5085c170c1dd673788a9f48c96cf13102be93", "parents": [ "9d90e49da57fe73a2f35334fdd2fb60dbf3933ed" ], "author": { "name": "KOSAKI Motohiro", "email": "kosaki.motohiro@jp.fujitsu.com", "time": "Fri Apr 15 20:39:01 2011 +0900" }, "committer": { "name": "Ingo Molnar", "email": "mingo@elte.hu", "time": "Fri Apr 15 20:28:19 2011 +0200" }, "message": "x86, NUMA: Fix fakenuma boot failure\n\nCurrently, numa\u003dfake boot parameter is broken.

That said, if a process under cpu\ncgroup promote RT scheduling class, the process never run at all.\n\nIf an admin inserts a !RT process into a cpu cgroup by setting\nrtruntime\u003d0, usually it runs perfectly because a !RT task isn\u0027t affected\nby the rtruntime knob.

In short,\nthe oom killer doesn\u0027t work at all if admins are using cpu cgroup and don\u0027t\ntouch the rtruntime knob.\n\nEventually, kernel may hang up when oom kill occur.

Look,\n\n\tstruct zone {\n\t ..\n\t int all_unreclaimable;\n\t ..\n\t unsigned long pages_scanned;\n\t ..\n\t}\n\nzone-\u003eall_unreclaimable and zone-\u003epages_scanned are neigher atomic\nvariables nor protected by lock. Therefore zones can become a state of\nzone-\u003epage_scanned\u003d0 and zone-\u003eall_unreclaimable\u003d1. In this case, current\nall_unreclaimable() return false even though zone-\u003eall_unreclaimabe\u003d1.\n\nThis resulted in the kernel hanging up when executing a loop of the form\n\n1. fork\n2. mmap\n3. touch memory\n4. read memory\n5. munmmap\n\nas described in\nhttp://www.gossamer-threads.com/lists/linux/kernel/1348725#1348725\n\nIs this ignorable minor issue? No. Unfortunately, x86 has very small dma\nzone and it become zone-\u003eall_unreclamble\u003d1 easily. and if it become\nall_unreclaimable\u003d1, it never restore all_unreclaimable\u003d0. Why? if\nall_unreclaimable\u003d1, vmscan only try DEF_PRIORITY reclaim and\na-few-lru-pages\u003e\u003eDEF_PRIORITY always makes 0. that mean no page scan at\nall!\n\nEventually, oom-killer never works on such systems. That said, we can\u0027t\nuse zone-\u003epages_scanned for this purpose. This patch restore\nall_unreclaimable() use zone-\u003eall_unreclaimable as old. and in addition,\nto add oom_killer_disabled check to avoid reintroduce the issue of commit\nd1908362 (\"vmscan: check all_unreclaimable in direct reclaim path\").\n\nReported-by: Andrey Vagin \u003cavagin@openvz.org\u003e\nSigned-off-by: KOSAKI Motohiro \u003ckosaki.motohiro@jp.fujitsu.com\u003e\nCc: Nick Piggin \u003cnpiggin@kernel.dk\u003e\nReviewed-by: Minchan Kim \u003cminchan.kim@gmail.com\u003e\nReviewed-by: KAMEZAWA Hiroyuki \u003ckamezawa.hiroyu@jp.fujitsu.com\u003e\nAcked-by: David Rientjes \u003crientjes@google.com\u003e\nCc: \u003cstable@kernel.org\u003e\nSigned-off-by: Andrew Morton \u003cakpm@linux-foundation.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@linux-foundation.org\u003e\n" }, { "commit": "fe936dfc23fed3475b11067e8d9b70553eafcd9e", "tree": "b45ad916853194b26bfe4504879e0bff64a43bf7", "parents": [ "4471a675dfc7ca676c165079e91c712b09dc9ce4" ], "author": { "name": "Michael Ellerman", "email": "michael@ellerman.id.au", "time": "Thu Apr 14 15:22:10 2011 -0700" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@linux-foundation.org", "time": "Thu Apr 14 16:06:55 2011 -0700" }, "message": "mm: check that we have the right vma in __access_remote_vm()\n\nIn __access_remote_vm() we need to check that we have found the right\nvma, not the following vma before we try to access it.
