**调用者**
名称	描述
fprop_new_period	Declare @periods new periods. It is upto the caller to make sure period* transitions cannot happen in parallel.* The function returns true if the proportions are still defined and false* if aging zeroed out all events
psi_group_change
psi_memstall_tick
do_settimeofday64	do_settimeofday64 - Sets the time of day.@ts: pointer to the timespec64 variable containing the new time Sets the time of day to the new time and update NTP and notify hrtimers
timekeeping_inject_offset	mekeeping_inject_offset - Adds or subtracts from the current time.@tv: pointer to the timespec variable containing the offset Adds or subtracts an offset value from the current time.
change_clocksource	hange_clocksource - Swaps clocksources if a new one is available* Accumulates current time interval and initializes new clocksource
timekeeping_init	初始化系统时钟计时
timekeeping_resume	mekeeping_resume - Resumes the generic timekeeping subsystem.
timekeeping_suspend
timekeeping_advance	mekeeping_advance - Updates the timekeeper to the current time and* current NTP tick length
do_adjtimex	do_adjtimex() - Accessor function to NTP __do_adjtimex function
cpuset_change_task_nodemask	puset_change_task_nodemask - change task's mems_allowed and mempolicy@tsk: the task to change@newmems: new nodes that the task will be set* We use the mems_allowed_seq seqlock to safely update both tsk->mems_allowed

__d_move	__d_move - move a dentry@dentry: entry to move@target: new dentry@exchange: exchange the two dentries Update the dcache to reflect the move of a file name
set_fs_root	Replace the fs->{rootmnt,root} with {mnt,dentry}. Put the old values.* It can block.
set_fs_pwd	Replace the fs->{pwdmnt,pwd} with {mnt,dentry}. Put the old values.* It can block.
chroot_fs_refs
userfaultfd_ctx_read
write_seqlock	当前CPU负责更新时间
write_seqlock_bh
