The most\ncommon trigger for this is network cards configured for jumbo frames but\nit\u0027s also possible it\u0027ll be triggered by fork-heavy workloads (order-1)\nand some wireless cards which depend on order-1 allocations.\n\nThe symptoms for the user will be high CPU usage by kswapd in low-memory\nsituations which could be confused with another writeback problem. While\na patch like 5a03b051 may be reintroduced in the future, this patch plays\nit safe for now and reverts it.\n\n[mel@csn.ul.ie: Beefed up the changelog]\nSigned-off-by: Andrea Arcangeli \u003caarcange@redhat.com\u003e\nSigned-off-by: Mel Gorman \u003cmel@csn.ul.ie\u003e\nReported-by: Arthur Marsh \u003carthur.marsh@internode.on.net\u003e\nTested-by: Arthur Marsh \u003carthur.marsh@internode.on.net\u003e\nCc: \u003cstable@kernel.org\u003e\t\t[2.6.38.1]\nSigned-off-by: Andrew Morton \u003cakpm@linux-foundation.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@linux-foundation.org\u003e\n" }, { "commit": "89699605fe7cfd8611900346f61cb6cbf179b10a", "tree": "5970232526d3b3715704bb6f90742e033802c3aa", "parents": [ "ef0a5e80f56f6409e957e7117da9551c3d3ff239" ], "author": { "name": "Nick Piggin", "email": "npiggin@suse.de", "time": "Tue Mar 22 16:30:36 2011 -0700" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@linux-foundation.org", "time": "Tue Mar 22 17:44:00 2011 -0700" }, "message": "mm: vmap area cache\n\nProvide a free area cache for the vmalloc virtual address allocator, based\non the algorithm used by the user virtual memory allocator.\n\nThis reduces the number of rbtree operations and linear traversals over\nthe vmap extents in order to find a free area, by starting off at the last\npoint that a free area was found.\n\nThe free area cache is reset if areas are freed behind it, or if we are\nsearching for a smaller area or alignment than last time. So allocation\npatterns are not changed (verified by corner-case and random test cases in\nuserspace testing).\n\nThis solves a regression caused by lazy vunmap TLB purging introduced in\ndb64fe02 (mm: rewrite vmap layer). That patch will leave extents in the\nvmap allocator after they are vunmapped, and until a significant number\naccumulate that can be flushed in a single batch. So in a workload that\nvmalloc/vfree frequently, a chain of extents will build up from\nVMALLOC_START address, which have to be iterated over each time (giving an\nO(n) type of behaviour).\n\nAfter this patch, the search will start from where it left off, giving\ncloser to an amortized O(1).\n\nThis is verified to solve regressions reported Steven in GFS2, and Avi in\nKVM.\n\nHugh\u0027s update:\n\n: I tried out the recent mmotm, and on one machine was fortunate to hit\n: the BUG_ON(first-\u003eva_start \u003c addr) which seems to have been stalling\n: your vmap area cache patch ever since May.\n\n: I can get you addresses etc, I did dump a few out; but once I stared\n: at them, it was easier just to look at the code: and I cannot see how\n: you would be so sure that first-\u003eva_start \u003c addr, once you\u0027ve done\n: that addr \u003d ALIGN(max(...), align) above, if align is over 0x1000\n: (align was 0x8000 or 0x4000 in the cases I hit: ioremaps like Steve).\n\n: I originally got around it by just changing the\n: \t\tif (first-\u003eva_start \u003c addr) {\n: to\n: \t\twhile (first-\u003eva_start \u003c addr) {\n: without thinking about it any further; but that seemed unsatisfactory,\n: why would we want to loop here when we\u0027ve got another very similar\n: loop just below it?\n\n: I am never going to admit how long I\u0027ve spent trying to grasp your\n: \"while (n)\" rbtree loop just above this, the one with the peculiar\n: \t\tif (!first \u0026\u0026 tmp-\u003eva_start \u003c addr + size)\n: in. That\u0027s unfamiliar to me, I\u0027m guessing it\u0027s designed to save a\n: subsequent rb_next() in a few circumstances (at risk of then setting\n: a wrong cached_hole_size?); but they did appear few to me, and I didn\u0027t\n: feel I could sign off something with that in when I don\u0027t grasp it,\n: and it seems responsible for extra code and mistaken BUG_ON below it.\n\n: I\u0027ve reverted to the familiar rbtree loop that find_vma() does (but\n: with va_end \u003e\u003d addr as you had, to respect the additional guard page):\n: and then (given that cached_hole_size starts out 0) I don\u0027t see the\n: need for any complications below it. If you do want to keep that loop\n: as you had it, please add a comment to explain what it\u0027s trying to do,\n: and where addr is relative to first when you emerge from it.\n\n: Aren\u0027t your tests \"size \u003c\u003d cached_hole_size\" and\n: \"addr + size \u003e first-\u003eva_start\" forgetting the guard page we want\n: before the next area? I\u0027ve changed those.\n\n: I have not changed your many \"addr + size - 1 \u003c addr\" overflow tests,\n: but have since come to wonder, shouldn\u0027t they be \"addr + size \u003c addr\"\n: tests - won\u0027t the vend checks go wrong if addr + size is 0?\n\n: I have added a few comments - Wolfgang Wander\u0027s 2.6.13 description of\n: 1363c3cd8603a913a27e2995dccbd70d5312d8e6 Avoiding mmap fragmentation\n: helped me a lot, perhaps a pointer to that would be good too. And I found\n: it easier to understand when I renamed cached_start slightly and moved the\n: overflow label down.\n\n: This patch would go after your mm-vmap-area-cache.patch in mmotm.\n: Trivially, nobody is going to get that BUG_ON with this patch, and it\n: appears to work fine on my machines; but I have not given it anything like\n: the testing you did on your original, and may have broken all the\n: performance you were aiming for.

This is\ndetected by PF_EXITING since threads that have already detached its -\u003emm\nare no longer considered at all.\n\nThe problem with always deferring when a thread is PF_EXITING, however, is\nthat it may never actually exit when being traced, specifically if another\ntask is tracing it with PTRACE_O_TRACEEXIT.

If a process is oom killed and the thread group\nleader exits, select_bad_process() cannot detect the other threads that\nare PF_EXITING by iterating over only processes. Thus, it currently\nchooses another task unnecessarily for oom kill or panics the machine when\nnothing else is eligible.\n\nBy iterating over threads instead, it is possible to detect threads that\nare exiting and nominate them for oom kill so they get access to memory\nreserves.\n\nSecond, cef1d352 (oom: multi threaded process coredump don\u0027t make\ndeadlock) erroneously avoids making the oom killer a no-op when an\neligible thread other than current isfound to be exiting. We want to\ndetect this situation so that we may allow that exiting thread time to\nexit and free its memory; if it is able to exit on its own, that should\nfree memory so current is no loner oom.
