名称描述
slab_alloc_nodeInlined fastpath so that allocation functions (kmalloc, kmem_cache_alloc)* have the fastpath folded into their functions. So no function call* overhead for requests that can be satisfied on the fastpath.
do_slab_freeFastpath with forced inlining to produce a kfree and kmem_cache_free that* can perform fastpath freeing without additional function calls.* The fastpath is only possible if we are freeing to the current cpu slab* of this processor
