| |
From: Paul Jackson <pj@sgi.com>
Change the kmem_cache_create calls for certain slab caches to support cpuset memory spreading.
See the previous patches, cpuset_mem_spread, for an explanation of cpuset memory spreading, and cpuset_mem_spread_slab_cache for the slab cache support for memory spreading.
The slag caches marked for now are: dentry_cache, inode_cache, and buffer_head. This list may change over time.
