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

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.
