The reason that this capability was removed was that\nthis could result in your kernel being pretty much useless, as rcutorture\nwould be running starting from early boot. This problem has been avoided\nby (1) making rcutorture run only three seconds of every six by default,\n(2) adding a CONFIG_RCU_TORTURE_TEST_RUNNABLE that permits rcutorture\nto be quiesced at boot time, and (3) adding a sysctl in /proc named\n/proc/sys/kernel/rcutorture_runnable that permits rcutorture to be\nquiesced and unquiesced when built into the kernel.\n\nPlease note that this /proc file is -not- available when rcutorture\nis built as a module.

The child becomes the new root node. To perform this\noperation in a manner compatible with concurrent lockless lookups, we\natomically switch the root pointer from the parent to its child.\n\nHowever a concurrent lockless lookup may now have loaded a pointer to the\nparent (and is presently deciding what to do next). For this reason, we\nalso have to keep the parent node in a valid state after shrinking the\ntree, until the next RCU grace period -- otherwise this lookup with the\nparent pointer may not do the right thing. Notably, we need to keep the\nchild in the left most slot there in case that is requested by the lookup.\n\nThis is all pretty standard RCU stuff. It is worth repeating because in\nmy eagerness to obey the radix tree node constructor scheme, I had broken\nit by zeroing the radix tree node before the grace period.\n\nWhat could happen is that a lookup can load the parent pointer, then\ndecide it wants to follow the left most child slot, only to find the slot\ncontained NULL due to the concurrent shrinker having zeroed the parent\nnode before waiting for a grace period. The lookup would return a false\nnegative as a result.\n\nFix it by doing that clearing in the RCU callback. I would normally want\nto rip out the constructor entirely, but radix tree nodes are one of those\nplaces where they make sense (only few cachelines will be touched soon\nafter allocation).\n\nThis was never actually found in any lockless pagecache testing or by the\ntest harness, but by seeing the odd problem with my scalable vmap rewrite.\n I have not tickled the test harness into reproducing it yet, but I\u0027ll\nkeep working at it.\n\nFortunately, it is not a problem anywhere lockless pagecache is used in\nmainline kernels (pagecache probe is not a guarantee, and brd does not\nhave concurrent lookups and deletes).\n\nSigned-off-by: Nick Piggin \u003cnpiggin@suse.de\u003e\nAcked-by: Peter Zijlstra \u003ca.p.zijlstra@chello.nl\u003e\nCc: \"Paul E.

One problem spot are\nkernel timers, where the detection of the problem often happens in interrupt\ncontext and usually causes the machine to panic.\n\nWhile working on a timer related bug report I had to hack specialized code\ninto the timer subsystem to get a reasonable hint for the root cause. This\ndebug hack was fine for temporary use, but far from a mergeable solution due\nto the intrusiveness into the timer code.\n\nThe code further lacked the ability to detect and report the root cause\ninstantly and keep the system operational.\n\nKeeping the system operational is important to get hold of the debug\ninformation without special debugging aids like serial consoles and special\nknowledge of the bug reporter.\n\nThe problems described above are not restricted to timers, but timers tend to\nexpose it usually in a full system crash. Other objects are less explosive,\nbut the symptoms caused by such mistakes can be even harder to debug.\n\nInstead of creating specialized debugging code for the timer subsystem a\ngeneric infrastructure is created which allows developers to verify their code\nand provides an easy to enable debug facility for users in case of trouble.\n\nThe debugobjects core code keeps track of operations on static and dynamic\nobjects by inserting them into a hashed list and sanity checking them on\nobject operations and provides additional checks whenever kernel memory is\nfreed.\n\nThe tracked object operations are:\n- initializing an object\n- adding an object to a subsystem list\n- deleting an object from a subsystem list\n\nEach operation is sanity checked before the operation is executed and the\nsubsystem specific code can provide a fixup function which allows to prevent\nthe damage of the operation. When the sanity check triggers a warning message\nand a stack trace is printed.\n\nThe list of operations can be extended if the need arises. For now it\u0027s\nlimited to the requirements of the first user (timers).\n\nThe core code enqueues the objects into hash buckets. The hash index is\ngenerated from the address of the object to simplify the lookup for the check\non kfree/vfree. Each bucket has it\u0027s own spinlock to avoid contention on a\nglobal lock.\n\nThe debug code can be compiled in without being active. The runtime overhead\nis minimal and could be optimized by asm alternatives. A kernel command line\noption enables the debugging code.\n\nThanks to Ingo Molnar for review, suggestions and cleanup patches.\n\nSigned-off-by: Thomas Gleixner \u003ctglx@linutronix.de\u003e\nSigned-off-by: Ingo Molnar \u003cmingo@elte.hu\u003e\nCc: Greg KH \u003cgreg@kroah.com\u003e\nCc: Randy Dunlap \u003crandy.dunlap@oracle.com\u003e\nCc: Kay Sievers \u003ckay.sievers@vrfy.org\u003e\nSigned-off-by: Andrew Morton \u003cakpm@linux-foundation.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@linux-foundation.org\u003e\n" }, { "commit": "a42dde04152750426cc620fd277e80fffae2f65a", "tree": "98cdf246280c59e0bf044ae6d2c229fc27b73203", "parents": [ "189d3c4a94ef19fca2a71a6a336e9fda900e25e7" ], "author": { "name": "Peter Zijlstra", "email": "a.p.zijlstra@chello.nl", "time": "Wed Apr 30 00:54:36 2008 -0700" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@linux-foundation.org", "time": "Wed Apr 30 08:29:50 2008 -0700" }, "message": "mm: bdi: allow setting a maximum for the bdi dirty limit\n\nAdd \"max_ratio\" to /sys/class/bdi.

If the\nn-th bit in the origin mask is set, then the m-th bit of the destination mask\nwill be set, where m is the position of the n-th set bit in the relative mask.\n\nThe bitmap_fold() operator folds a bitmap into a second that has bit m set iff\nthe input bitmap has some bit n set, where m \u003d\u003d n mod sz, for the specified sz\nvalue.\n\nThere are two substantive changes between this patch and its\npredecessor bitmap_relative:\n 1) Renamed bitmap_relative() to be bitmap_onto().\n 2) Added bitmap_fold().\n\nThe essential motivation for bitmap_onto() is to provide a mechanism for\nconverting a cpuset-relative CPU or Node mask to an absolute mask. Cpuset\nrelative masks are written as if the current task were in a cpuset whose CPUs\nor Nodes were just the consecutive ones numbered 0..N-1, for some N. The\nbitmap_onto() operator is provided in anticipation of adding support for the\nfirst such cpuset relative mask, by the mbind() and set_mempolicy() system\ncalls, using a planned flag of MPOL_F_RELATIVE_NODES. These bitmap operators\n(and their nodemask wrappers, in particular) will be used in code that\nconverts the user specified cpuset relative memory policy to a specific system\nnode numbered policy, given the current mems_allowed of the tasks cpuset.\n\nSuch cpuset relative mempolicies will address two deficiencies\nof the existing interface between cpusets and mempolicies:\n 1) A task cannot at present reliably establish a cpuset\n relative mempolicy because there is an essential race\n condition, in that the tasks cpuset may be changed in\n between the time the task can query its cpuset placement,\n and the time the task can issue the applicable mbind or\n set_memplicy system call.\n 2) A task cannot at present establish what cpuset relative\n mempolicy it would like to have, if it is in a smaller\n cpuset than it might have mempolicy preferences for,\n because the existing interface only allows specifying\n mempolicies for nodes currently allowed by the cpuset.\n\nCpuset relative mempolicies are useful for tasks that don\u0027t distinguish\nparticularly between one CPU or Node and another, but only between how many of\neach are allowed, and the proper placement of threads and memory pages on the\nvarious CPUs and Nodes available.\n\nThe motivation for the added bitmap_fold() can be seen in the following\nexample.\n\nLet\u0027s say an application has specified some mempolicies that presume 16 memory\nnodes, including say a mempolicy that specified MPOL_F_RELATIVE_NODES (cpuset\nrelative) nodes 12-15. Then lets say that application is crammed into a\ncpuset that only has 8 memory nodes, 0-7.
