名称描述
flush_slab
___slab_allocSlow path. The lockless freelist is empty or we need to perform* debugging duties.* Processing is still very fast if new objects have been freed to the* regular freelist. In that case we simply take over the regular freelist
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
kmem_cache_alloc_bulkNote that interrupts must be enabled when calling this function.
