alloc_cpu_rmap - allocate CPU affinity reverse-map : Number of objects to be mapped : Allocation flags e.g. GFP_KERNEL

Definition at line 30 of file cpu_rmap.c.

int cpu_rmap_add	(	struct cpu_rmap *	rmap,
		void *	obj
	)

cpu_rmap_add - add object to a rmap : CPU rmap allocated with alloc_cpu_rmap() : Object to add to rmap

Return index of object.
