**调用者**
名称	描述
test_find_first_bit	This is Schlemiel the Painter's algorithm. It should be called after* all other tests for the same bitmap because it sets all bits of bitmap to 1.
test_find_next_bit
test_find_next_zero_bit
test_find_last_bit
test_find_next_and_bit
test_func
__test_bitmap_parselist
aperfmperf_get_khz
arch_freq_prepare_all
arch_freq_get_on_cpu
async_run_entry_fn	pick the first pending entry and run it
async_synchronize_cookie_domain	async_synchronize_cookie_domain - synchronize asynchronous function calls within a certain domain with cookie checkpointing@cookie: async_cookie_t to use as checkpoint@domain: the domain to synchronize (%NULL for all registered domains)* This function
sched_debug_header
hibernate_preallocate_memory	hibernate_preallocate_memory - Preallocate memory for hibernation image
save_image	save_image - save the suspend image data
save_image_lzo	save_image_lzo - Save the suspend image data compressed with LZO.@handle: Swap map handle to use for saving the image.@snapshot: Image to read data from.*@nr_to_write: Number of pages to save.
load_image	load_image - load the image using the swap map handle@handle and the snapshot handle @snapshot (assume there are @nr_pages pages to load)
load_image_lzo	load_image_lzo - Load compressed image data and decompress them with LZO.@handle: Swap map handle to use for loading data.@snapshot: Image to copy uncompressed data into.*@nr_to_read: Number of pages to load.
wakelock_lookup_add
usleep_range	sleep_range - Sleep for an approximate time@min: Minimum time in usecs to sleep@max: Maximum time in usecs to sleep* In non-atomic context where the exact wakeup time is flexible, use* usleep_range() instead of udelay()
sysrq_timer_list_show
timer_list_start
clockevents_program_min_delta	lockevents_program_min_delta - Set clock event device to the minimum delay.@dev: device to program Returns 0 on success, -ETIME when the retry loop failed.
clockevents_program_event	设置下一次触发时间
tick_setup_device	Setup the tick device
tick_resume_oneshot	k_resume_onshot - resume oneshot mode
SYSCALL_DEFINE6
ring_buffer_producer
torture_shutdown	Cause the torture test to shutdown the system after the test has* run for the time specified by the shutdown_secs parameter.
torture_shutdown_init	Start up the shutdown task.
trace_initcall_finish_cb
__gup_benchmark_ioctl
blkcg_iolatency_done_bio
blkiolatency_timer_fn
iolatency_pd_init
ioc_now	ake a snapshot of the current [v]time and vrate
blk_iocost_init
bfq_set_budget_timeout	Set the maximum time for the in-service queue to consume its* budget. This prevents seeky processes from lowering the throughput.* In practice, a time-slice service scheme is used with seeky* processes.
bfq_arm_slice_timer
bfq_bfqq_is_slow	Return true if the process associated with bfqq is "slow". The slow* flag is used, in addition to the budget timeout, to reduce the* amount of service provided to seeky processes, and thus reduce* their chances to lower the throughput
rwb_sync_issue_lat
aperfmperf_snapshot_khz	aperfmperf_snapshot_khz()* On the current CPU, snapshot APERF, MPERF, and jiffies* unless we already did it within 10ms* calculate kHz, save snapshot
trace_initcall_start_cb
ktime_get_ns
tick_nohz_get_next_hrtimer
dim_update_sample	dim_update_sample - set a sample's fields with given values@event_ctr: number of events to set@packets: number of packets to set@bytes: number of bytes to set@s: DIM sample
blkcg_maybe_throttle_blkg	This is called when we want to actually walk up the hierarchy and check to* see if we need to throttle, and then actually throttle if there is some* accumulated delay. This should only be called upon return to user space so
