• 94f6030ca   Slab allocators: Replace explicit zeroing with __GFP_ZERO ... Browse Code »

  kmalloc_node() and kmem_cache_alloc_node() were not available in a zeroing
  variant in the past. But with __GFP_ZERO it is possible now to do zeroing
  while allocating.

  Use __GFP_ZERO to remove the explicit clearing of memory via memset whereever
  we can.

• a12058687   [PATCH] Allow NULL pointers in percpu_free ... Browse Code »

  The patch (as824b) makes percpu_free() ignore NULL arguments, as one would
  expect for a deallocation routine. (Note that free_percpu is #defined as
  percpu_free in include/linux/percpu.h.) A few callers are updated to remove
  now-unneeded tests for NULL. A few other callers already seem to assume
  that passing a NULL pointer to percpu_free() is okay!

  The patch also removes an unnecessary NULL check in percpu_depopulate().

• d00bcc98d   [PATCH] Extract the allocpercpu functions from the slab allocator ... Browse Code »

  The allocpercpu functions __alloc_percpu and __free_percpu() are heavily
  using the slab allocator. However, they are conceptually slab. This also
  simplifies SLOB (at this point slob may be broken in mm. This should fix
  it).
