For this\nreason the memory bitmap structure consists of several linked lists of objects\nthat contain pointers to memory pages with the actual bitmap data.

Slab reclaim is then used as a final\noption if the freeing of unmapped file backed pages is not enough to free\nenough pages to allow a local allocation.\n\nHowever, that means that the slab can grow excessively and that most memory\nof a node may be used by slabs. We have had a case where a machine with\n46GB of memory was using 40-42GB for slab. Zone reclaim was effective in\ndealing with pagecache pages. However, slab reclaim was only done during\nglobal reclaim (which is a bit rare on NUMA systems).\n\nThis patch implements slab reclaim during zone reclaim. Zone reclaim\noccurs if there is a danger of an off node allocation. At that point we\n\n1. Shrink the per node page cache if the number of pagecache\n pages is more than min_unmapped_ratio percent of pages in a zone.\n\n2. Shrink the slab cache if the number of the nodes reclaimable slab pages\n (patch depends on earlier one that implements that counter)\n are more than min_slab_ratio (a new /proc/sys/vm tunable).\n\nThe shrinking of the slab cache is a bit problematic since it is not node\nspecific. So we simply calculate what point in the slab we want to reach\n(current per node slab use minus the number of pages that neeed to be\nallocated) and then repeately run the global reclaim until that is\nunsuccessful or we have reached the limit.

If it cannot\npull any tasks away from the busiest cpu because they were pinned then the\nscheduler goes into a corner and sulks leaving the idle processors idle.\n\nF.e. If you have processor 0 busy running four tasks pinned via taskset,\nthere are none on processor 1 and one just started two processes on\nprocessor 2 then the scheduler will not move one of the two processes away\nfrom processor 2.\n\nThis patch fixes that issue by forcing the scheduler to come out of its\ncorner and retrying the load balancing by considering other processors for\nload balancing.\n\nThis patch was originally developed by John Hawkes and discussed at\n\n http://marc.theaimsgroup.com/?l\u003dlinux-kernel\u0026m\u003d113901368523205\u0026w\u003d2.\n\nI have removed extraneous material and gone back to equipping struct rq\nwith the cpu the queue is associated with since this makes the patch much\neasier and it is likely that others in the future will have the same\ndifficulty of figuring out which processor owns which runqueue.\n\nThe overhead added through these patches is a single word on the stack if\nthe kernel is configured to support 32 cpus or less (32 bit). For 32 bit\nenvironments the maximum number of cpus that can be configued is 255 which\nwould result in the use of 32 bytes additional on the stack. On IA64 up to\n1k cpus can be configured which will result in the use of 128 additional\nbytes on the stack. The maximum additional cache footprint is one\ncacheline. Typically memory use will be much less than a cacheline and the\nadditional cpumask will be placed on the stack in a cacheline that already\ncontains other local variable.\n\nSigned-off-by: Christoph Lameter \u003cclameter@sgi.com\u003e\nCc: John Hawkes \u003chawkes@sgi.com\u003e\nCc: \"Siddha, Suresh B\" \u003csuresh.b.siddha@intel.com\u003e\nCc: Ingo Molnar \u003cmingo@elte.hu\u003e\nCc: Nick Piggin \u003cnickpiggin@yahoo.com.au\u003e\nCc: Peter Williams \u003cpwil3058@bigpond.net.au\u003e\nCc: \u003cstable@kernel.org\u003e\nSigned-off-by: Andrew Morton \u003cakpm@osdl.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@osdl.org\u003e\n" }, { "commit": "adf1423698f00d00b267f7dca8231340ce7d65ef", "tree": "ec2e28a32d467cc3c618c8ee0cedd3d1a49f9c43", "parents": [ "ab2e0b46cb9a197fab7d98e147cac7cd41a14047" ], "author": { "name": "Jan Beulich", "email": "jbeulich@novell.com", "time": "Tue Sep 26 10:52:41 2006 +0200" }, "committer": { "name": "Andi Kleen", "email": "andi@basil.nowhere.org", "time": "Tue Sep 26 10:52:41 2006 +0200" }, "message": "[PATCH] i386/x86-64: Work around gcc bug with noreturn functions in unwinder\n\nCurrent gcc generates calls not jumps to noreturn functions.

This is due to buggy logic in the use of\nfutex_handle_fault() and its attempt argument in a failure case.\n\nLooking at futex.c the logic is as follows:\n\n1) In futex_unlock_pi() we start w/ ret\u003d0 and we go down to the first\n futex_atomic_cmpxchg_inatomic(), where we find uval\u003d\u003d-EFAULT. We then\n jump to the pi_faulted label.\n\n2) From pi_faulted: We increment attempt, unlock the sem and hit the\n retry label.\n\n3) From the retry label, with ret still zero, we again hit EFAULT on the\n first futex_atomic_cmpxchg_inatomic(), and again goto the pi_faulted\n label.\n\n4) Again from pi_faulted: we increment attempt and enter the\n conditional, where we call futex_handle_fault.\n\n5) futex_handle_fault fails, and we goto the out_unlock_release_sem\n label.\n\n6) From out_unlock_release_sem we return, and since ret is still zero,\n we return without error, while never actually unlocking the lock.\n\nIssue #1: at the first futex_atomic_cmpxchg_inatomic() we should probably\nbe setting ret\u003d-EFAULT before jumping to pi_faulted: However in our case\nthis doesn\u0027t really affect anything, as the glibc we\u0027re using ignores the\nerror value from futex_unlock_pi().\n\nIssue #2: Look at futex_handle_fault(), its first conditional will return\n-EFAULT if attempt is \u003e\u003d 2. However, from the \"if(attempt++)\nfutex_handle_fault(attempt)\" logic above, we\u0027ll *never* call\nfutex_handle_fault when attempt is less then two. So we never get a chance\nto even try to fault the page in.\n\nThe following patch addresses these two issues by 1) Always setting ret to\n-EFAULT if futex_handle_fault fails, and 2) Removing the \u003d in\nfutex_handle_fault\u0027s (attempt \u003e\u003d 2) check.\n\nI\u0027m really not sure this is the right fix, but wanted to bring it up so\nfolks knew the issue is alive and well in the current -git tree.

On a\nIA_64 test machine (Itanium-2 1.6 GHz) running a benchmark like netperf\u0027s\nUDP streaming test, the added overhead results in a drop of 3% in\nthroughput, as udp_sendmsg calls the local_bh_enable/disable several times.\n\nOther workloads that have heavy usages of local_bh_enable/disable could\nalso be affected.
