名称	描述
irq_poll_cpu_dead
list_test_list_splice_init
swake_up_all	Does not allow usage from IRQ disabled, since we must be able to* release IRQs to guarantee bounded hold time.
__free_zapped_classes	The caller must hold the graph lock. May be called from RCU context.
cgroup_migrate_execute	group_taskset_migrate - migrate a taskset@mgctx: migration context Migrate tasks in @mgctx as setup by migration preparation functions.* This function fails iff one of the ->can_attach callbacks fails and

bpf_offload_dev_netdev_unregister
perf_addr_filters_splice
slab_caches_to_rcu_destroy_workfn
merge_queues	merge_queues - merge single semop queues into global queue@sma: semaphore array This function merges all per-semaphore queues into the global queue.* It is necessary to achieve FIFO ordering for the pending single-sop
flush_plug_callbacks
ioc_clear_queue	_clear_queue - break any ioc association with the specified queue@q: request_queue being cleared Walk @q->icq_list and exit all io_cq's.
blk_softirq_cpu_dead
blk_mq_requeue_work
blk_mq_dispatch_rq_list	Returns true if we did some work AND can potentially do more.
blk_mq_flush_plug_list
blk_mq_hctx_notify_dead	'cpu' is going away. splice any existing rq_list entries from this* software queue to the hw queue dispatch list, and ensure that it* gets run.

namespace_unlock
queue_io	Queue all expired dirty inodes for io, eldest first.* Before* newly dirtied b_dirty b_io b_more_io* =============> gf edc BA* After* newly dirtied b_dirty b_io b_more_io* =============> g fBAedc* \|* +--> dequeue for IO
wait_sb_inodes	The @s_sync_lock is used to serialise concurrent sync operations* to avoid lock contention problems with concurrent wait_sb_inodes() calls.* Concurrent callers will block on the s_sync_lock rather than doing contending* walks
ep_scan_ready_list	p_scan_ready_list - Scans the ready list in a way that makes possible for* the scan code, to call f_op->poll(). Also allows for* O(NumReady) performance.@ep: Pointer to the epoll private data structure.@sproc: Pointer to the scan callback.
