NAME
kmem_cache_alloc_node - Allocate an object on the specified node
SYNOPSIS
void * kmem_cache_alloc_node (kmem_cache_t * cachep, gfp_t flags,
int nodeid);
ARGUMENTS
cachep The cache to allocate from.
flags See kmalloc.
nodeid node number of the target node.
DESCRIPTION
Identical to kmem_cache_alloc, except that this function is slow and
can sleep. And it will allocate memory on the given node, which can
improve the performance for cpu bound structures.
NEW AND IMPROVED
it will now make sure that the object gets put on the correct node list
so that there is no false sharing.
