You would have to\n  grep the entire kernel for things that check slab_is_available() and\n  even then you\u0027ll be missing some.\n\n  For example, slab_is_available() didn\u0027t always exist, and so in the\n  early days on powerpc, we used a mem_init_done global that is set form\n  mem_init() (not perfect but works in practice). And we still have code\n  using that to do the test.\n\nTherefore, mask out __GFP_WAIT, __GFP_IO, and __GFP_FS in the slab allocators\nin early boot code to avoid enabling interrupts.\n\nSigned-off-by: Pekka Enberg \u003cpenberg@cs.helsinki.fi\u003e\n"

      "message": "infrastructure to debug (dynamic) objects\n\nWe can see an ever repeating problem pattern with objects of any kind in the\nkernel:\n\n1) freeing of active objects\n2) reinitialization of active objects\n\nBoth problems can be hard to debug because the crash happens at a point where\nwe have no chance to decode the root cause anymore.  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"

The inconsistency\nmakes it difficult to implement in derived allocators such as in the uncached\nallocator and the pool allocators.\n\nIn addition the support zeroed allocations in the slab allocators does not\nhave a consistent API.  There are no zeroing allocator functions for NUMA node\nplacement (kmalloc_node, kmem_cache_alloc_node).  The zeroing allocations are\nonly provided for default allocs (kzalloc, kmem_cache_zalloc_node).\n__GFP_ZERO will make zeroing universally available and does not require any\naddititional functions.\n\nSo add the necessary logic to all slab allocators to support __GFP_ZERO.\n\nThe code is added to the hot path.  The gfp flags are on the stack and so the\ncacheline is readily available for checking if we want a zeroed object.\n\nZeroing while allocating is now a frequent operation and we seem to be\ngradually approaching a 1-1 parity between zeroing and not zeroing allocs.\nThe current tree has 3476 uses of kmalloc vs 2731 uses of kzalloc.\n\nSigned-off-by: Christoph Lameter \u003cclameter@sgi.com\u003e\nAcked-by: Pekka Enberg \u003cpenberg@cs.helsinki.fi\u003e\nSigned-off-by: Andrew Morton \u003cakpm@linux-foundation.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@linux-foundation.org\u003e\n"

Unfortunately, it neglected to\nensure that the _second_ redzone, after the slab object, is aligned\ncorrectly. This caused illegal instruction faults on sparc32, which for\nsome reason not entirely clear to me are not trapped and fixed up.\n\nTwo things need to be done to fix this:\n  - increase the object size, rounding up to alignof(long long) so\n    that the second redzone can be aligned correctly.\n  - If SLAB_STORE_USER is set but alignof(long long)\u003d\u003d8, allow a\n    full 64 bits of space for the user word at the end of the buffer,\n    even though we may not _use_ the whole 64 bits.\n\nThis patch should be a no-op on any 64-bit architecture or any 32-bit\narchitecture where alignof(long long) \u003d\u003d 4.
