Doing this under the protection of the locks guarantees the\nsynchronization is correct, and also means that spurious faults which are\ngenerated during this window by remote CPUs are properly handled, as the page\nfault handler must re-check the PTE under protection of the same lock.\n\nSigned-off-by: Zachary Amsden \u003czach@vmware.com\u003e\nSigned-off-by: Jeremy Fitzhardinge \u003cjeremy@xensource.com\u003e\nCc: Rusty Russell \u003crusty@rustcorp.com.au\u003e\nCc: Andi Kleen \u003cak@suse.de\u003e\nSigned-off-by: Andrew Morton \u003cakpm@osdl.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@osdl.org\u003e\n" }, { "commit": "9888a1cae3f859db38b9604e3df1c02177161bb0", "tree": "5954dc5e1a2dc1251a57a41aa15b7776a530f230", "parents": [ "3dc907951446b9317b1887223caa4e083390de9f" ], "author": { "name": "Zachary Amsden", "email": "zach@vmware.com", "time": "Sat Sep 30 23:29:31 2006 -0700" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@g5.osdl.org", "time": "Sun Oct 01 00:39:33 2006 -0700" }, "message": "[PATCH] paravirt: pte clear not present\n\nChange pte_clear_full to a more appropriately named pte_clear_not_present,\nallowing optimizations when not-present mapping changes need not be reflected\nin the hardware TLB for protected page table modes.

Make this top cpus file read-only.\n\nOn systems that have cpusets configured in their kernel, but that aren\u0027t\nactively using cpusets (for some distros, this covers the majority of\nsystems) all tasks end up in the top cpuset.\n\nIf that system does support memory hotplug, then these tasks cannot make\nuse of memory nodes that are added after system boot, because the memory\nnodes are not allowed in the top cpuset. This is a surprising regression\nover earlier kernels that didn\u0027t have cpusets enabled.\n\nOne key motivation for this change is to remain consistent with the\nbehaviour for the top_cpuset\u0027s \u0027cpus\u0027, which is also read-only, and which\nautomatically tracks the cpu_online_map.\n\nThis change also has the minor benefit that it fixes a long standing,\nlittle noticed, minor bug in cpusets. The cpuset performance tweak to\nshort circuit the cpuset_zone_allowed() check on systems with just a single\ncpuset (see \u0027number_of_cpusets\u0027, in linux/cpuset.h) meant that simply\nchanging the \u0027mems\u0027 of the top_cpuset had no affect, even though the change\n(the write system call) appeared to succeed. With the following change,\nthat write to the \u0027mems\u0027 file fails -EACCES, and the \u0027mems\u0027 file stubbornly\nrefuses to be changed via user space writes. Thus no one should be mislead\ninto thinking they\u0027ve changed the top_cpusets\u0027s \u0027mems\u0027 when in affect they\nhaven\u0027t.\n\nIn order to keep the behaviour of cpusets consistent between systems\nactively making use of them and systems not using them, this patch changes\nthe behaviour of the \u0027mems\u0027 file in the top (root) cpuset, making it read\nonly, and making it automatically track the value of node_online_map. Thus\ntasks in the top cpuset will have automatic use of hot plugged memory nodes\nallowed by their cpuset.\n\n[akpm@osdl.org: build fix]\n[bunk@stusta.de: build fix]\nSigned-off-by: Paul Jackson \u003cpj@sgi.com\u003e\nSigned-off-by: Adrian Bunk \u003cbunk@stusta.de\u003e\nSigned-off-by: Andrew Morton \u003cakpm@osdl.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@osdl.org\u003e\n" }, { "commit": "b78483a4ba60d5d90930262a533a784e1d9df660", "tree": "0b2cb0f3cf2852bf4138c13179221e58a37f402a", "parents": [ "01017a227044d64face2588fab9427a1da1bdb9f" ], "author": { "name": "Nick Piggin", "email": "npiggin@suse.de", "time": "Fri Sep 29 02:01:14 2006 -0700" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@g5.osdl.org", "time": "Fri Sep 29 09:18:21 2006 -0700" }, "message": "[PATCH] oom: don\u0027t kill current when another OOM in progress\n\nA previous patch to allow an exiting task to OOM kill itself (and thereby\navoid a little deadlock) introduced a problem.

All slab allocations use\nGFP_THISNODE when calling into the page allocator. If an allocation fails\nthen we fall back in the slab allocator according to the zonelists appropriate\nfor a certain context.\n\nThis allows a replication of the behavior of alloc_pages and alloc_pages node\nin the slab layer.\n\nCurrently allocations requested from the page allocator may be redirected via\ncpusets to other nodes. This results in remote pages on nodelists and that in\nturn results in interrupt latency issues during cache draining. Plus the slab\nis handing out memory as local when it is really remote.\n\nFallback for slab memory allocations will occur within the slab allocator and\nnot in the page allocator. This is necessary in order to be able to use the\nexisting pools of objects on the nodes that we fall back to before adding more\npages to a slab.\n\nThe fallback function insures that the nodes we fall back to obey cpuset\nrestrictions of the current context.

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.

This occurs because\nenable_cpucache() fails if it cannot reallocate some caches.\n\nHowever, enable_cpucache() is used for multiple purposes: resizing caches,\ncache creation and bootstrap.\n\nIf the slab is already up then we already have working caches. The resize\ncan fail without a problem.
