[PATCH 0/6] treewide: kmem_cache_alloc GFP_ZERO cleanups

[Joe Perches]

Just a few cleanups to use zalloc style calls and reduce
the uses of __GFP_ZERO for kmem_cache_alloc[_node] uses.

Use the more kernel normal zalloc style.

Joe Perches (6):
  slab/block: Add and use kmem_cache_zalloc_node
  block: Convert kmem_cache_alloc(...GFP_ZERO) to kmem_cache_zalloc
  i915_gem: Convert kmem_cache_alloc(...GFP_ZERO) to kmem_cache_zalloc
  aio: Convert kmem_cache_alloc(...GFP_ZERO) to kmem_cache_zalloc
  ceph: Convert kmem_cache_alloc(...GFP_ZERO) to kmem_cache_zalloc
  f2fs: Convert kmem_cache_alloc(...GFP_ZERO) to kmem_cache_zalloc

[PATCH 4/6] aio: Convert kmem_cache_alloc(...GFP_ZERO) to kmem_cache_zalloc

[Joe Perches]

The helper exists, might as well use it instead of __GFP_ZERO.
