Presently on UP NUMA this has the side-effect of preferring\nnode#0 allocations (since numa_node_id() \u003d\u003d 0, though this could be\nreworked if we could hand off a pfn to determine node placement), so\nsingle-CPU NUMA systems will want to place smaller nodes further out in\nterms of node id. Once a page has been bound to a node (via explicit node\nid typing), we only do block allocations from partial free pages that have\na matching node id in the page flags.\n\nThe current implementation does have some scalability problems, in that all\npartial free pages are tracked in the global freelist (with contention due\nto the single spinlock).

Allocation can be slightly faster too, because we can\n skip almost-full freelist pages completely.\n\n- Slob pages are then freed immediately when they become empty, rather than\n having a periodic timer try to free them. This gives efficiency and memory\n consumption improvement.\n\nThen, we don\u0027t encode seperate size and next fields into each slob block,\nrather we use the sign bit to distinguish between \"size\" or \"next\". Then\nsize 1 blocks contain a \"next\" offset, and others contain the \"size\" in\nthe first unit and \"next\" in the second unit.\n\n- This allows minimum slob allocation alignment to go from 8 bytes to 2\n bytes on 32-bit and 12 bytes to 2 bytes on 64-bit. In practice, it is\n best to align them to word size, however some architectures (eg. cris)\n could gain space savings from turning off this extra alignment.\n\nThen, make kmalloc use its own slob_block at the front of the allocation\nin order to encode allocation size, rather than rely on not overwriting\nslob\u0027s existing header block.\n\n- This reduces kmalloc allocation overhead similarly to alignment reductions.\n\n- Decouples kmalloc layer from the slob allocator.\n\nThen, add a page flag specific to slob pages.\n\n- This means kfree of a page aligned slob block doesn\u0027t have to traverse\n the bigblock list.\n\nI would get benchmarks, but my test box\u0027s network doesn\u0027t come up with\nslob before this patch. I think something is timing out.

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. Of the others, it\u0027s tested\non ppc32 by myself and a very similar patch was tested on sparc32 by\nMark Fortescue, who reported the new problem.\n\nAlso, fix the conditions for FORCED_DEBUG, which hadn\u0027t been adjusted to\nthe new sizes.

This patch avoids that need by moving all free\nobjects onto a lockless_freelist. The regular freelist continues to exist\nand will be used to free objects. So while we consume the\nlockless_freelist the regular freelist may build up objects.\n\nIf we are out of objects on the lockless_freelist then we may check the\nregular freelist. If it has objects then we move those over to the\nlockless_freelist and do this again. There is a significant savings in\nterms of atomic operations that have to be performed.\n\nWe can even free directly to the lockless_freelist if we know that we are\nrunning on the same processor. So this speeds up short lived objects.\nThey may be allocated and freed without taking the slab_lock. This is\nparticular good for netperf.\n\nIn order to maximize the effect of the new faster hotpath we extract the\nhottest performance pieces into inlined functions. These are then inlined\ninto kmem_cache_alloc and kmem_cache_free. So hotpath allocation and\nfreeing no longer requires a subroutine call within SLUB.\n\n[I am not sure that it is worth doing this because it changes the easy to\nread structure of slub just to reduce atomic ops. However, there is\nsomeone out there with a benchmark on 4 way and 8 way processor systems\nthat seems to show a 5% regression vs. Slab. Seems that the regression is\ndue to increased atomic operations use vs. SLAB in SLUB).

The cache reaper does only exists in SLUB as a way to\nprovide compatibility with SLAB.

This will lead to some overlap in large\nsystems. F.e a system running at 250 HZ with 1024 processors will have 4 vm\nupdates occurring at once.\n\nHowever, the vm stats update only accesses per node information.

The leaked count can permanently trap N\nnumber of hugetlb pages in unusable \"reserved\" state.\n\nSteps to reproduce the bug:\n\n (1) create two cpuset, user1 and user2\n (2) reserve 50 htlb pages in cpuset user1\n (3) attempt to shmget/shmat 50 htlb page inside cpuset user2\n (4) kernel oom the user process in step 3\n (5) ipcrm the shm segment\n\nAt this point resv_huge_pages will have a count of 49, even though\nthere are no active hugetlbfs file nor hugetlb shared memory segment\nin the system. The leak is permanent and there is no recovery method\nother than system reboot. The leaked count will hold up all future use\nof that many htlb pages in all cpusets.\n\nThe culprit is that the error path of alloc_huge_page() did not\nproperly undo the change it made to resv_huge_page, causing\ninconsistent state.\n\nSigned-off-by: Ken Chen \u003ckenchen@google.com\u003e\nCc: David Gibson \u003cdavid@gibson.dropbear.id.au\u003e\nCc: Adam Litke \u003cagl@us.ibm.com\u003e\nCc: Martin Bligh \u003cmbligh@google.com\u003e\nAcked-by: David Gibson \u003cdwg@au1.ibm.com\u003e\nCc: \u003cstable@kernel.org\u003e\nSigned-off-by: Andrew Morton \u003cakpm@linux-foundation.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@linux-foundation.org\u003e\n" }, { "commit": "7ae439ce0c01d7db0c70d1542985969e95ef750d", "tree": "7da3778be3e1c80cd834bf72dc33c3c82ff43017", "parents": [ "5e6d444ea1f72b8148354a9baf0ea8fa3dd0425b" ], "author": { "name": "Pekka J Enberg", "email": "penberg@cs.helsinki.fi", "time": "Wed May 09 02:32:46 2007 -0700" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@woody.linux-foundation.org", "time": "Wed May 09 12:30:46 2007 -0700" }, "message": "krealloc: fix kerneldoc comments\n\nNo \"blank\" (or \"*\") line is allowed between the function name and lines for\nit parameter(s).\n\nCc: Randy Dunlap \u003crandy.dunlap@oracle.com\u003e\nSigned-off-by: Pekka Enberg \u003cpenberg@cs.helsinki.fi\u003e\nCc: Christoph Lameter \u003cclameter@sgi.com\u003e\nSigned-off-by: Andrew Morton \u003cakpm@linux-foundation.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@linux-foundation.org\u003e\n" }, { "commit": "5e6d444ea1f72b8148354a9baf0ea8fa3dd0425b", "tree": "c9c07fd97acd925bfb9c4964240799414243d399", "parents": [ "45edfa580b8e638c44ec26872bfe75b307ba12d1" ], "author": { "name": "Christoph Lameter", "email": "clameter@sgi.com", "time": "Wed May 09 02:32:46 2007 -0700" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@woody.linux-foundation.org", "time": "Wed May 09 12:30:46 2007 -0700" }, "message": "SLUB: rework slab order determination\n\nIn some cases SLUB is creating uselessly slabs that are larger than\nslub_max_order.
