**调用者**
名称	描述
rdtgroup_move_task
_do_fork	分裂进程
mm_update_next_owner	A task is exiting. If it owned this mm, find a new owner for the mm.
wait_task_zombie	Handle sys_wait4 work for one task in state EXIT_ZOMBIE. We hold* read_lock(&tasklist_lock) on entry. If we return zero, we still hold* the lock and this task is uninteresting. If we return nonzero, we have
wait_task_stopped	wait_task_stopped - Wait for %TASK_STOPPED or %TASK_TRACED@wo: wait options@ptrace: is the wait for ptrace@p: task to wait for Handle sys_wait4() work for %p in state %TASK_STOPPED or %TASK_TRACED
wait_task_continued	Handle do_wait work for one task in a live, non-stopped state.* read_lock(&tasklist_lock) on entry. If we return zero, we still hold* the lock and this task is uninteresting. If we return nonzero, we have
SYSCALL_DEFINE4
find_get_task_by_vpid
get_pid_task
kthread_stop	结束线程的运行
__smpboot_create_thread
wake_q_add	wake_q_add() - queue a wakeup for 'later' waking
do_sched_setscheduler
SYSCALL_DEFINE3	sys_sched_setattr - same as above, but with extended sched_attr@pid: the pid in question.@uattr: structure containing the extended parameters.*@flags: for future extension.
sched_setaffinity
task_non_contending	The utilization of a task cannot be immediately removed from* the rq active utilization (running_bw) when the task blocks
start_dl_timer	If the entity depleted all its runtime, and if we want it to sleep* while waiting for some new execution time to become available, we* set the bandwidth replenishment timer to the replenishment instant* and try to activate it
rwsem_mark_wake	handle the lock release when processes blocked on it that can now run* - if we come here from up_xxxx(), then the RWSEM_FLAG_WAITERS bit must* have been set
rt_mutex_adjust_prio_chain	Adjust the priority chain
task_blocks_on_rt_mutex	Task blocks on lock.* Prepare waiter and propagate pi chain* This must be called with lock->wait_lock held and interrupts disabled
remove_waiter	Remove a waiter from a lock and give up* Must be called with lock->wait_lock held and interrupts disabled. I must* have just failed to try_to_take_rt_mutex().
rt_mutex_adjust_pi	Recheck the pi chain, in case we got a priority setting* Called from sched_setscheduler
setup_irq_thread
SYSCALL_DEFINE5
__get_task_for_clock
mark_wake_futex	The hash bucket lock must be held when this is called.* Afterwards, the futex_q must not be accessed. Callers* must ensure to later call wake_up_q() for the actual* wakeups to occur.
cgroup_procs_write_start
css_task_iter_next	ss_task_iter_next - return the next task for the iterator@it: the task iterator being iterated The "next" function for task iteration. @it should have been* initialized via css_task_iter_start(). Returns NULL when the iteration* reaches the end.
cgroup_transfer_tasks	group_trasnsfer_tasks - move tasks from one cgroup to another@to: cgroup to which the tasks will be moved@from: cgroup in which the tasks currently reside* Locking rules between cgroup_post_fork() and the migration path* guarantee that, if a task is
rcu_lock_break	To avoid extending the RCU grace period for an unbounded amount of time,* periodically exit the critical section and enter a new one.* For preemptible RCU it is sufficient to call rcu_read_unlock in order* to exit the grace period
probe_wakeup
alloc_perf_context
find_lively_task_by_vpid
perf_remove_from_owner	Remove user event from the owner task.
perf_event_alloc	Allocate and initialize an event structure
oom_evaluate_task
wake_oom_reaper
__oom_kill_process
oom_kill_memcg_member	Kill provided task unless it's secured by setting* oom_score_adj to OOM_SCORE_ADJ_MIN.
out_of_memory	_of_memory - kill the "best" process when we run out of memory@oc: pointer to struct oom_control If we run out of memory, we have the choice between either* killing a random task (bad), letting the system crash (worse)
swap_readpage
kernel_migrate_pages
kernel_move_pages	Move a list of pages in the address space of the currently executing* process.
add_to_kill	Schedule a process for later kill.* Uses GFP_ATOMIC allocations to avoid potential recursions in the VM.
report_access	defers execution because cmdline access can sleep
yama_task_prctl	yama_task_prctl - check for Yama-specific prctl operations@option: operation@arg2: argument@arg3: argument@arg4: argument@arg5: argument Return 0 on success, -ve on error. -ENOSYS is returned when Yama* does not handle the given option.
