The cacheline that\nholds the per cpu array pointer now also holds these values. We can cut down\nthe struct kmem_cache_cpu size to almost half.\n\nThe get_freepointer() and set_freepointer() functions that used to be only\nintended for the slow path now are also useful for the hot path since access\nto the size field does not require accessing an additional cacheline anymore.\nThis results in consistent use of functions for setting the freepointer of\nobjects throughout SLUB.\n\nAlso we initialize all possible kmem_cache_cpu structures when a slab is\ncreated. No need to initialize them when a processor or node comes online.\n\nSigned-off-by: Christoph Lameter \u003ccl@linux-foundation.org\u003e\nSigned-off-by: Pekka Enberg \u003cpenberg@cs.helsinki.fi\u003e\n" }, { "commit": "756dee75872a2a764b478e18076360b8a4ec9045", "tree": "c4a09707be2f926631815dec98b0e0f3f4b9ae20", "parents": [ "9dfc6e68bfe6ee452efb1a4e9ca26a9007f2b864" ], "author": { "name": "Christoph Lameter", "email": "cl@linux-foundation.org", "time": "Fri Dec 18 16:26:21 2009 -0600" }, "committer": { "name": "Pekka Enberg", "email": "penberg@cs.helsinki.fi", "time": "Sun Dec 20 09:57:00 2009 +0200" }, "message": "SLUB: Get rid of dynamic DMA kmalloc cache allocation\n\nDynamic DMA kmalloc cache allocation is troublesome since the\nnew percpu allocator does not support allocations in atomic contexts.\nReserve some statically allocated kmalloc_cpu structures instead.\n\nSigned-off-by: Christoph Lameter \u003ccl@linux-foundation.org\u003e\nSigned-off-by: Pekka Enberg \u003cpenberg@cs.helsinki.fi\u003e\n" }, { "commit": "9dfc6e68bfe6ee452efb1a4e9ca26a9007f2b864", "tree": "40e54f2819e176ceb95b8899265bd48751965c27", "parents": [ "55639353a0035052d9ea6cfe4dde0ac7fcbb2c9f" ], "author": { "name": "Christoph Lameter", "email": "cl@linux-foundation.org", "time": "Fri Dec 18 16:26:20 2009 -0600" }, "committer": { "name": "Pekka Enberg", "email": "penberg@cs.helsinki.fi", "time": "Sun Dec 20 09:29:18 2009 +0200" }, "message": "SLUB: Use this_cpu operations in slub\n\nUsing per cpu allocations removes the needs for the per cpu arrays in the\nkmem_cache struct.

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" }, { "commit": "512626a04e72aca60effe111fa0333ed0b195d21", "tree": "c22e23b0dcc2dd2ff5a9a96a007de6799e9223de", "parents": [ "8a1ca8cedd108c8e76a6ab34079d0bbb4f244799", "3aa27bbe7a6536d1ec859d3a97caf3319b5081b7" ], "author": { "name": "Linus Torvalds", "email": "torvalds@linux-foundation.org", "time": "Thu Jun 11 14:15:57 2009 -0700" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@linux-foundation.org", "time": "Thu Jun 11 14:15:57 2009 -0700" }, "message": "Merge branch \u0027for-linus\u0027 of git://linux-arm.org/linux-2.6\n\n* \u0027for-linus\u0027 of git://linux-arm.org/linux-2.6:\n kmemleak: Add the corresponding MAINTAINERS entry\n kmemleak: Simple testing module for kmemleak\n kmemleak: Enable the building of the memory leak detector\n kmemleak: Remove some of the kmemleak false positives\n kmemleak: Add modules support\n kmemleak: Add kmemleak_alloc callback from alloc_large_system_hash\n kmemleak: Add the vmalloc memory allocation/freeing hooks\n kmemleak: Add the slub memory allocation/freeing hooks\n kmemleak: Add the slob memory allocation/freeing hooks\n kmemleak: Add the slab memory allocation/freeing hooks\n kmemleak: Add documentation on the memory leak detector\n kmemleak: Add the base support\n\nManual conflict resolution (with the slab/earlyboot changes) in:\n\tdrivers/char/vt.c\n\tinit/main.c\n\tmm/slab.c\n" }, { "commit": "83b519e8b9572c319c8e0c615ee5dd7272856090", "tree": "ecf130629f6228d509bb52c533ca2287f966f972", "parents": [ "c91c4773b334d4d3a6d44626dc2a558ad97b86f3" ], "author": { "name": "Pekka Enberg", "email": "penberg@cs.helsinki.fi", "time": "Wed Jun 10 19:40:04 2009 +0300" }, "committer": { "name": "Pekka Enberg", "email": "penberg@cs.helsinki.fi", "time": "Thu Jun 11 19:15:56 2009 +0300" }, "message": "slab: setup allocators earlier in the boot sequence\n\nThis patch makes kmalloc() available earlier in the boot sequence so we can get\nrid of some bootmem allocations.
