This is in contrast to -ENOMEM\n injection. So fine configurability isn\u0027t required.\n\n- The fault injection framework only allows to set a simple\n probability for failure. Now the probability that a ww mutex acquire\n stage with N locks will never complete (due to too many injected\n EDEADLK backoffs) is zero. But the expected number of ww_mutex_lock\n operations for the completely uncontended case would be O(exp(N)).\n The per-acuiqire ctx exponential backoff solution choosen here only\n results in O(log N) overhead due to injection and so O(log N * N)\n lock operations. This way we can fail with high probability (and so\n have good test coverage even for fancy backoff and lock acquisition\n paths) without running into patalogical cases.\n\nNote that EDEADLK will only ever be injected when we managed to\nacquire the lock.

But in\norder to know how many read shares to grant, we must first count the\nreaders at the head of the queue. This might take a while if there are\nmany readers, and we want to be protected against a writer stealing the\nlock while we\u0027re counting. To that end, we grant the first reader lock\nbefore counting how many more readers are queued.\n\nWe also require some adjustments to the wake_type semantics.\n\nRWSEM_WAKE_NO_ACTIVE used to mean that we had found the count to be\nRWSEM_WAITING_BIAS, in which case the rwsem was known to be free as\nnobody could steal it while we hold the wait_lock.

On some archs, dump_stack() prints\nextra information - pid, utsname and so on - in addition to the\nbacktrace while the two are identical on other archs.\n\nThe usages in arch-independent code of the two functions indicate\nshow_stack(NULL, NULL) should print out bare backtrace while\ndump_stack() is used for debugging purposes when something went wrong,\nso it does make sense to print additional information on the task which\ntriggered dump_stack().\n\nThere\u0027s no reason to require archs to implement two separate but mostly\nidentical functions. It leads to unnecessary subtle information.\n\nThis patch expands the dummy fallback dump_stack() implementation in\nlib/dump_stack.c such that it prints out debug information (taken from\nx86) and invokes show_stack(NULL, NULL) and drops arch-specific\ndump_stack() implementations in all archs except blackfin. Blackfin\u0027s\ndump_stack() does something wonky that I don\u0027t understand.\n\nDebug information can be printed separately by calling\ndump_stack_print_info() so that arch-specific dump_stack()\nimplementation can still emit the same debug information. This is used\nin blackfin.\n\nThis patch brings the following behavior changes.\n\n* On some archs, an extra level in backtrace for show_stack() could be\n printed. This is because the top frame was determined in\n dump_stack() on those archs while generic dump_stack() can\u0027t do that\n reliably. It can be compensated by inlining dump_stack() but not\n sure whether that\u0027d be necessary.\n\n* Most archs didn\u0027t use to print debug info on dump_stack(). They do\n now.\n\nAn example WARN dump follows.\n\n WARNING: at kernel/workqueue.c:4841 init_workqueues+0x35/0x505()\n Hardware name: empty\n Modules linked in:\n CPU: 0 PID: 1 Comm: swapper/0 Not tainted 3.9.0-rc1-work+ #9\n 0000000000000009 ffff88007c861e08 ffffffff81c614dc ffff88007c861e48\n ffffffff8108f50f ffffffff82228240 0000000000000040 ffffffff8234a03c\n 0000000000000000 0000000000000000 0000000000000000 ffff88007c861e58\n Call Trace:\n [\u003cffffffff81c614dc\u003e] dump_stack+0x19/0x1b\n [\u003cffffffff8108f50f\u003e] warn_slowpath_common+0x7f/0xc0\n [\u003cffffffff8108f56a\u003e] warn_slowpath_null+0x1a/0x20\n [\u003cffffffff8234a071\u003e] init_workqueues+0x35/0x505\n ...\n\nv2: CPU number added to the generic debug info as requested by s390\n folks and dropped the s390 specific dump_stack(). This loses %ksp\n from the debug message which the maintainers think isn\u0027t important\n enough to keep the s390-specific dump_stack() implementation.\n\n dump_stack_print_info() is moved to kernel/printk.c from\n lib/dump_stack.c. Because linkage is per objecct file,\n dump_stack_print_info() living in the same lib file as generic\n dump_stack() means that archs which implement custom dump_stack()\n - at this point, only blackfin - can\u0027t use dump_stack_print_info()\n as that will bring in the generic version of dump_stack() too. v1\n The v1 patch broke build on blackfin due to this issue.

The module.c code was introduced in\n commit 6494a93d55fa\"\n\nAnatol supplied a patch specific for module.c that worked around the\nproblem by simply not using kset_find_obj() at all, but rather than make\na local band-aid, this just fixes kset_find_obj() to be thread-safe\nusing the proper model of refusing the get a new reference if the\nrefcount has already dropped to zero.\n\nSee examples of this proper refcount handling not only in the kref\ndocumentation, but in various other equivalent uses of this pattern by\ngrepping for atomic_inc_not_zero().\n\n[ Side note: the module race does indicate that module loading and\n unloading is not properly serialized wrt sysfs information using the\n module mutex. That may require further thought, but this is the\n correct fix at the kobject layer regardless. ]\n\nReported-analyzed-and-tested-by: Anatol Pomozov \u003canatol.pomozov@gmail.com\u003e\nCc: Greg Kroah-Hartman \u003cgregkh@linuxfoundation.org\u003e\nCc: Al Viro \u003cviro@zeniv.linux.org.uk\u003e\nCc: stable@vger.kernel.org\nSigned-off-by: Linus Torvalds \u003ctorvalds@linux-foundation.org\u003e\n" }, { "commit": "0ecc833bac594099505a090cbca6ccd5b83d5975", "tree": "399f524f078636335aeb465f805eff6ed27137b1", "parents": [ "aee0c612b12f57f4923f6649fa6fcba618182261" ], "author": { "name": "Al Viro", "email": "viro@zeniv.linux.org.uk", "time": "Fri Mar 29 12:23:28 2013 -0400" }, "committer": { "name": "Al Viro", "email": "viro@zeniv.linux.org.uk", "time": "Tue Apr 09 14:13:05 2013 -0400" }, "message": "mode_t, whack-a-mole at 11...\n\nSigned-off-by: Al Viro \u003cviro@zeniv.linux.org.uk\u003e\n" }, { "commit": "ecb135a1a1953d2895d149e78926be479fdc6f2c", "tree": "e40aa30eefa5cc42ed1169b9798810a710a1bd9a", "parents": [ "bd6946e87a98fea11907b2a47368e13044458a35", "07961ac7c0ee8b546658717034fe692fd12eefa9" ], "author": { "name": "Daniel Vetter", "email": "daniel.vetter@ffwll.ch", "time": "Wed Apr 03 11:25:32 2013 +0200" }, "committer": { "name": "Daniel Vetter", "email": "daniel.vetter@ffwll.ch", "time": "Wed Apr 03 11:28:48 2013 +0200" }, "message": "Merge tag \u0027v3.9-rc5\u0027 into drm-intel-next-queued\n\nBackmerge Linux 3.9-rc5 since I want to merge a few dp clock cleanups\nfor -next, but they will conflict all over the place with\n\ncommit 9d1a455b0ca1c2c956b4d9ab212864a8695270f1\nAuthor: Takashi Iwai \u003ctiwai@suse.de\u003e\nDate: Mon Mar 18 11:25:36 2013 +0100\n\n drm/i915: Use the fixed pixel clock for eDP in intel_dp_set_m_n()\n\nfrom -fixes.\n\nConflicts:\n\tdrivers/gpu/drm/i915/intel_dp.c: Simply adjacent lines changed.\n\tdrivers/gpu/drm/i915/intel_panel.c: A field rename in -next\n\tconflicts with a bugfix in -fixes.
