It is therefore time to\nenlist the aid of lockdep.\n\nThis set of patches is inspired by earlier work by Peter\nZijlstra and Thomas Gleixner, and takes the following approach:\n\no\tSet up separate lockdep classes for RCU, RCU-bh, and RCU-sched.\n\no\tSet up separate lockdep classes for each instance of SRCU.\n\no\tCreate primitives that check for being in an RCU read-side\n\tcritical section. These return exact answers if lockdep is\n\tfully enabled, but if unsure, report being in an RCU read-side\n\tcritical section. (We want to avoid false positives!)\n\tThe primitives are:\n\n\tFor RCU: rcu_read_lock_held(void)\n\n\tFor RCU-bh: rcu_read_lock_bh_held(void)\n\n\tFor RCU-sched: rcu_read_lock_sched_held(void)\n\n\tFor SRCU: srcu_read_lock_held(struct srcu_struct *sp)\n\no\tAdd rcu_dereference_check(), which takes a second argument\n\tin which one places a boolean expression based on the above\n\tprimitives and/or lockdep_is_held().\n\no\tA new kernel configuration parameter, CONFIG_PROVE_RCU, enables\n\trcu_dereference_check(). This depends on CONFIG_PROVE_LOCKING,\n\tand should be quite helpful during the transition period while\n\tCONFIG_PROVE_RCU-unaware patches are in flight.\n\nThe existing rcu_dereference() primitive does no checking, but\nupcoming patches will change that.\n\nSigned-off-by: Paul E.

This solves two problems:\n\n (1) In SYSV SHM where nattch for a segment does not reflect the number of\n shmat\u0027s (and forks) done.\n\n (2) In mmap() where the VMA\u0027s vm_mm is set to point to the parent mm by an\n exec\u0027ing process when VM_EXECUTABLE is specified, regardless of the fact\n that a VMA might be shared and already have its vm_mm assigned to another\n process or a dead process.\n\nA new struct (vm_region) is introduced to track a mapped region and to remember\nthe circumstances under which it may be shared and the vm_list_struct structure\nis discarded as it\u0027s no longer required.\n\nThis patch makes the following additional changes:\n\n (1) Regions are now allocated with alloc_pages() rather than kmalloc() and\n with no recourse to __GFP_COMP, so the pages are not composite. Instead,\n each page has a reference on it held by the region. Anything else that is\n interested in such a page will have to get a reference on it to retain it.\n When the pages are released due to unmapping, each page is passed to\n put_page() and will be freed when the page usage count reaches zero.\n\n (2) Excess pages are trimmed after an allocation as the allocation must be\n made as a power-of-2 quantity of pages.\n\n (3) VMAs are added to the parent MM\u0027s R/B tree and mmap lists. As an MM may\n end up with overlapping VMAs within the tree, the VMA struct address is\n appended to the sort key.\n\n (4) Non-anonymous VMAs are now added to the backing inode\u0027s prio list.\n\n (5) Holes may be punched in anonymous VMAs with munmap(), releasing parts of\n the backing region. The VMA and region structs will be split if\n necessary.\n\n (6) sys_shmdt() only releases one attachment to a SYSV IPC shared memory\n segment instead of all the attachments at that addresss. Multiple\n shmat()\u0027s return the same address under NOMMU-mode instead of different\n virtual addresses as under MMU-mode.\n\n (7) Core dumping for ELF-FDPIC requires fewer exceptions for NOMMU-mode.\n\n (8) /proc/maps is now the global list of mapped regions, and may list bits\n that aren\u0027t actually mapped anywhere.\n\n (9) /proc/meminfo gains a line (tagged \"MmapCopy\") that indicates the amount\n of RAM currently allocated by mmap to hold mappable regions that can\u0027t be\n mapped directly. These are copies of the backing device or file if not\n anonymous.\n\nThese changes make NOMMU mode more similar to MMU mode. The downside is that\nNOMMU mode requires some extra memory to track things over NOMMU without this\npatch (VMAs are no longer shared, and there are now region structs).\n\nSigned-off-by: David Howells \u003cdhowells@redhat.com\u003e\nTested-by: Mike Frysinger \u003cvapier.adi@gmail.com\u003e\nAcked-by: Paul Mundt \u003clethal@linux-sh.org\u003e\n" }, { "commit": "da4276b8299a6544dc41ac2485d3ffca5811b3fb", "tree": "8225c30e900cadb4b5dee86a4f70b189cceb3c12", "parents": [ "0936912274af78a21fd8d54c3f94a50a285cf7f9" ], "author": { "name": "Ingo Molnar", "email": "mingo@elte.hu", "time": "Wed Jan 07 11:05:10 2009 +0100" }, "committer": { "name": "Ingo Molnar", "email": "mingo@elte.hu", "time": "Wed Jan 07 11:18:59 2009 +0100" }, "message": "x86: offer frame pointers in all build modes\n\nCONFIG_FRAME_POINTERS\u003dy results in much better debug info for the\nkernel (clear and precise backtraces), with the only drawback being\na ~1% increase in kernel size.\n\nSo offer it unconditionally and enable it by default.\n\nSigned-off-by: Ingo Molnar \u003cmingo@elte.hu\u003e\n" }, { "commit": "db5e53fbf0abf5cadc83be57032242e5e7c6c394", "tree": "e391aebab8b81a68fe36e5fef8a729062f643259", "parents": [ "3f4b5c5d275608d42ff54c4981307f9a5c75ea4a", "3c506efd7e0f615bd9603ce8c06bc4a896952599" ], "author": { "name": "Linus Torvalds", "email": "torvalds@linux-foundation.org", "time": "Tue Dec 30 17:28:09 2008 -0800" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@linux-foundation.org", "time": "Tue Dec 30 17:28:09 2008 -0800" }, "message": "Merge branch \u0027for-linus\u0027 of git://git.kernel.org/pub/scm/linux/kernel/git/penberg/slab-2.6\n\n* \u0027for-linus\u0027 of git://git.kernel.org/pub/scm/linux/kernel/git/penberg/slab-2.6:\n slub: avoid leaking caches or refcounts on sysfs error\n slab: Fix comment on #endif\n slab: remove GFP_THISNODE clearing from alloc_slabmgmt()\n slub: Add might_sleep_if() to slab_alloc()\n SLUB: failslab support\n slub: Fix incorrect use of loose\n slab: Update the kmem_cache_create documentation regarding the name parameter\n slub: make early_kmem_cache_node_alloc void\n slab: unsigned slabp-\u003einuse cannot be less than 0\n slub - fix get_object_page comment\n SLUB: Replace __builtin_return_address(0) with _RET_IP_.\n SLUB: cleanup - define macros instead of hardcoded numbers\n" }, { "commit": "773ff60e841461cb1f9374a713ffcda029b8c317", "tree": "c3691b5a82261a3d2c1861f2913774faac63fa96", "parents": [ "3c92ec8ae91ecf59d88c798301833d7cf83f2179" ], "author": { "name": "Akinobu Mita", "email": "akinobu.mita@gmail.com", "time": "Tue Dec 23 19:37:01 2008 +0900" }, "committer": { "name": "Pekka Enberg", "email": "penberg@cs.helsinki.fi", "time": "Mon Dec 29 11:27:46 2008 +0200" }, "message": "SLUB: failslab support\n\nCurrently fault-injection capability for SLAB allocator is only\navailable to SLAB.

In particular, this code\n\tno longer requires a proof of correctness. ;-)\n\no\tSeparated dynticks state out into its own per-CPU structure,\n\tavoiding the duplicated accounting.\n\no\tThe case where a dynticks-idle CPU runs an irq handler that\n\tinvokes call_rcu() is now correctly handled, forcing that CPU\n\tout of dynticks-idle mode.\n\no\tReview comments have been applied (thank you all!!!).\n\tFor but one example, fixed the dynticks-ordering issue that\n\tManfred pointed out, saving me much debugging. ;-)\n\no\tAdjusted rcuclassic and rcupreempt to handle dynticks changes.\n\nAttached is an updated patch to Classic RCU that applies a hierarchy,\ngreatly reducing the contention on the top-level lock for large machines.\nThis passes 10-hour concurrent rcutorture and online-offline testing on\n128-CPU ppc64 without dynticks enabled, and exposes some timekeeping\nbugs in presence of dynticks (exciting working on a system where\n\"sleep 1\" hangs until interrupted...), which were fixed in the\n2.6.27 kernel. It is getting more reliable than mainline by some\nmeasures, so the next version will be against -tip for inclusion.\nSee also Manfred Spraul\u0027s recent patches (or his earlier work from\n2004 at http://marc.info/?l\u003dlinux-kernel\u0026m\u003d108546384711797\u0026w\u003d2).\nWe will converge onto a common patch in the fullness of time, but are\ncurrently exploring different regions of the design space. That said,\nI have already gratefully stolen quite a few of Manfred\u0027s ideas.\n\nThis patch provides CONFIG_RCU_FANOUT, which controls the bushiness\nof the RCU hierarchy. Defaults to 32 on 32-bit machines and 64 on\n64-bit machines. If CONFIG_NR_CPUS is less than CONFIG_RCU_FANOUT,\nthere is no hierarchy. By default, the RCU initialization code will\nadjust CONFIG_RCU_FANOUT to balance the hierarchy, so strongly NUMA\narchitectures may choose to set CONFIG_RCU_FANOUT_EXACT to disable\nthis balancing, allowing the hierarchy to be exactly aligned to the\nunderlying hardware. Up to two levels of hierarchy are permitted\n(in addition to the root node), allowing up to 16,384 CPUs on 32-bit\nsystems and up to 262,144 CPUs on 64-bit systems. I just know that I\nam going to regret saying this, but this seems more than sufficient\nfor the foreseeable future. (Some architectures might wish to set\nCONFIG_RCU_FANOUT\u003d4, which would limit such architectures to 64 CPUs.\nIf this becomes a real problem, additional levels can be added, but I\ndoubt that it will make a significant difference on real hardware.)\n\nIn the common case, a given CPU will manipulate its private rcu_data\nstructure and the rcu_node structure that it shares with its immediate\nneighbors. This can reduce both lock and memory contention by multiple\norders of magnitude, which should eliminate the need for the strange\nmanipulations that are reported to be required when running Linux on\nvery large systems.\n\nSome shortcomings:\n\no\tMore bugs will probably surface as a result of an ongoing\n\tline-by-line code inspection.\n\n\tPatches will be provided as required.\n\no\tThere are probably hangs, rcutorture failures, \u0026c. Seems\n\tquite stable on a 128-CPU machine, but that is kind of small\n\tcompared to 4096 CPUs. However, seems to do better than\n\tmainline.\n\n\tPatches will be provided as required.\n\no\tThe memory footprint of this version is several KB larger\n\tthan rcuclassic.\n\n\tA separate UP-only rcutiny patch will be provided, which will\n\treduce the memory footprint significantly, even compared\n\tto the old rcuclassic. One such patch passes light testing,\n\tand has a memory footprint smaller even than rcuclassic.\n\tInitial reaction from various embedded guys was \"it is not\n\tworth it\", so am putting it aside.\n\nCredits:\n\no\tManfred Spraul for ideas, review comments, and bugs spotted,\n\tas well as some good friendly competition. ;-)\n\no\tJosh Triplett, Ingo Molnar, Peter Zijlstra, Mathieu Desnoyers,\n\tLai Jiangshan, Andi Kleen, Andy Whitcroft, and Andrew Morton\n\tfor reviews and comments.\n\no\tThomas Gleixner for much-needed help with some timer issues\n\t(see patches below).\n\no\tJon M.
