名称	描述
do_read
copy_process	创建进程
do_wait
ptrace_peek_siginfo
wants_signal	Test if P wants to take SIG. After we've checked all threads with this,* it's equivalent to finding no threads not blocking SIG. Any threads not* blocking SIG were ruled out because they are not running and already* have pending signals
retarget_shared_pending	It could be that complete_signal() picked us to notify about the* group-wide signal. Other threads should be notified now to take* the shared signals in @which since we will not.
exit_signals
__set_task_blocked
sys_pause
sigsuspend
do_wait_intr	Note! These two wait functions are entered with the* case), so there is no race with testing the wakeup* condition in the caller before they add the wait* entry to the wake queue.
do_wait_intr_irq
__rt_mutex_slowlock	__rt_mutex_slowlock() - Perform the wait-wake-try-to-take loop@lock: the rt_mutex to take@state: the state the task should block in (TASK_INTERRUPTIBLE* or TASK_UNINTERRUPTIBLE)@timeout: the pre-initialized and started timer, or NULL for none@waiter:
rcu_gp_fqs_loop	Loop doing repeated quiescent-state forcing until the grace period ends.
rcu_gp_kthread	Body of kthread that handles grace periods.
msleep_interruptible	msleep_interruptible - sleep waiting for signals*@msecs: Time in milliseconds to sleep for
do_nanosleep
do_cpu_nanosleep
futex_wait
handle_early_requeue_pi_wakeup	handle_early_requeue_pi_wakeup() - Detect early wakeup on the initial futex@hb: the hash_bucket futex_q was original enqueued on@q: the futex_q woken while waiting to be requeued@key2: the futex_key of the requeue target futex@timeout: the timeout
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
do_check
uprobe_deny_signal	If we are singlestepping, then ensure this thread is not connected to* non-fatal signals until completion of singlestep. When xol insn itself* triggers the signal, restart the original insn even if the task is
mm_take_all_locks	This operation locks against the VM for all pte/vma/mm related* operations that could ever happen on a certain mm. This includes* vmtruncate, try_to_unmap, and all page faults.* The caller must take the mmap_sem in write mode before calling
try_to_unuse	If the boolean frontswap is true, only unuse pages_to_unuse pages;* pages_to_unuse==0 means all pages; ignored if frontswap is false
set_max_huge_pages
unmerge_ksm_pages	Though it's very tempting to unmerge rmap_items from stable tree rather* than check every pte of a given vma, the locking doesn't quite work for* that - an rmap_item is assigned to the stable tree after inserting ksm* page and upping mmap_sem
mem_cgroup_resize_max
mem_cgroup_force_empty	Reclaims as many pages from the given memcg as possible.* Caller is responsible for holding css reference for memcg.
memory_high_write
memory_max_write
scan_should_stop	Memory scanning is a long process and it needs to be interruptable. This* function checks whether such interrupt condition occurred.
do_msgsnd
do_msgrcv
do_semtimedop
wq_sleep	Puts current task to sleep. Caller must hold queue lock. After return* lock isn't held.
blk_mq_poll_hybrid_sleep
pipe_write
wait_for_partner
filldir
filldir64
compat_filldir
do_select
core_sys_select	We can actually return ERESTARTSYS instead of EINTR, but I'd* like to be certain this leads to no problems. So I return* EINTR just for safety.* Update: ERESTARTSYS breaks at least the xview clock binary, so
do_poll
compat_core_sys_select	We can actually return ERESTARTSYS instead of EINTR, but I'd* like to be certain this leads to no problems. So I return* EINTR just for safety.* Update: ERESTARTSYS breaks at least the xview clock binary, so
splice_from_pipe_next	splice_from_pipe_next - wait for some data to splice from@pipe: pipe to splice from@sd: information about the splice operation* Description:* This function will wait for some data and return a positive* value (one) if pipe buffers are available
wait_for_space
ipipe_prep	Make sure there's data to read. Wait for input if we can, otherwise* return an appropriate error.
opipe_prep	Make sure there's writeable room. Wait for room if we can, otherwise* return an appropriate error.
inotify_read
fanotify_read
ep_poll	p_poll - Retrieves ready events, and delivers them to the caller supplied* event buffer.@ep: Pointer to the eventpoll context.@events: Pointer to the userspace buffer where the ready events should be* stored.
signalfd_dequeue
eventfd_read
eventfd_write
handle_userfault	The locking rules involved in returning VM_FAULT_RETRY depending on* FAULT_FLAG_ALLOW_RETRY, FAULT_FLAG_RETRY_NOWAIT and* FAULT_FLAG_KILLABLE are not straightforward
userfaultfd_ctx_read
SYSCALL_DEFINE6
COMPAT_SYSCALL_DEFINE6
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_worker_handle_work
io_wqe_worker
dump_interrupted
fatal_signal_pending
signal_pending_state
