名称	描述
usermodehelper_read_lock_wait
__cancel_work_timer
__wait_on_bit	To allow interruptible waiting and asynchronous (i.e. nonblocking)* waiting, the actions of __wait_on_bit() and __wait_on_bit_lock() are* permitted return codes. Nonzero return codes halt waiting and return.
__wait_on_bit_lock
cgroup_lock_and_drain_offline	group_lock_and_drain_offline - lock cgroup_mutex and drain offlined csses@cgrp: root of the target subtree Because css offlining is asynchronous, userland may try to re-enable a* controller while the previous css is still around. This function grabs
ring_buffer_wait	g_buffer_wait - wait for input to the ring buffer@buffer: buffer to wait on@cpu: the cpu buffer to wait on@full: wait until a full page is available, if @cpu != RING_BUFFER_ALL_CPUS If @cpu == RING_BUFFER_ALL_CPUS then the task will wake up as soon
mempool_alloc	mempool_alloc - allocate an element from a specific memory pool@pool: pointer to the memory pool which was allocated via mempool_create().@gfp_mask: the usual allocation bitmask. this function only sleeps if the alloc_fn() function sleeps or
kswapd_try_to_sleep
congestion_wait	gestion_wait - wait for a backing_dev to become uncongested@sync: SYNC or ASYNC IO@timeout: timeout in jiffies* Waits for up to @timeout jiffies for a backing_dev (any backing_dev) to exit* write congestion
wait_iff_congested	wait_iff_congested - Conditionally wait for a backing_dev to become uncongested or a pgdat to complete writes@sync: SYNC or ASYNC IO@timeout: timeout in jiffies* In the event of a congested backing_dev (any backing_dev) this waits* for up to @timeout
mem_cgroup_wait_acct_move
mem_cgroup_oom_synchronize	mem_cgroup_oom_synchronize - complete memcg OOM handling@handle: actually kill/wait or just clean up the OOM state This has to be called at the end of a page fault if the memcg OOM* handler was enabled
rq_qos_wait	q_qos_wait - throttle on a rqw if we need to@rqw: rqw to throttle on@private_data: caller provided specific data@acquire_inflight_cb: inc the rqw->inflight counter if we can@cleanup_cb: the callback to cleanup in case we race with a waker
ioc_rqos_throttle
__wait_on_freeing_inode
__inode_dio_wait	Direct i/o helper functions
inode_sleep_on_writeback	Sleep until I_SYNC is cleared. This function must be called with i_lock* held and drops it. It is aimed for callers not holding any inode reference* so once i_lock is dropped, inode can go away.
bd_prepare_to_claim	d_prepare_to_claim - prepare to claim a block device@bdev: block device of interest@whole: the whole device containing @bdev, may equal @bdev@holder: holder trying to claim @bdev Prepare to claim @bdev
io_sq_thread
io_cqring_wait	Wait until events become available, if we don't already have some. The* application must reap them itself, as they reside on the shared cq ring.
io_uring_cancel_files
get_unlocked_entry	Look up entry in page cache, wait for it to become unlocked if it* is a DAX entry and return it. The caller must subsequently call* put_unlocked_entry() if it did not lock the entry or dax_unlock_entry()* if it did
wait_entry_unlocked	The only thing keeping the address space around is the i_pages lock* (it's cycled in clear_inode() after removing the entries from i_pages)* After we call xas_unlock_irq(), we cannot touch xas->xa.
sbitmap_finish_wait
usermodehelper_read_trylock
wait_on_page_bit_common
pipe_wait	Drop the inode semaphore and wait for a pipe event, atomically
