**调用者**
名称	描述
vsscanf	vsscanf - Unformat a buffer into a list of arguments@buf: input buffer@fmt: format of buffer*@args: arguments
_parse_integer	Convert non-negative integer string representation in explicitly given radix* to an integer.* Return number of characters consumed maybe or-ed with overflow bit.* If overflow occurs, result integer (incorrect) is still returned.
div64_u64_rem	div64_u64_rem - unsigned 64bit divide with 64bit divisor and remainder@dividend: 64bit dividend@divisor: 64bit divisor@remainder: 64bit remainder This implementation is a comparable to algorithm used by div64_u64
div64_u64	div64_u64 - unsigned 64bit divide with 64bit divisor@dividend: 64bit dividend@divisor: 64bit divisor* This implementation is a modified version of the algorithm proposed* by the book 'Hacker's Delight'. The original source and full proof
FSE_normalizeM2	Secondary normalization method.To be used when primary method fails.
FSE_normalizeCount
rbtree_test_init
interval_tree_test_init
calibrate_APIC_clock
apbt_quick_calibrate	alled before apb_timer_enable, use early map
scale_stime	Perform (stime * rtime) / total, but avoid multiplication overflow by* losing precision when the numbers are big.
___update_load_avg
calc_avgs
collect_percpu_times
update_averages
psi_show
psi_trigger_create
psi_trigger_destroy
nsec_to_clock_t
nsecs_to_jiffies64	secs_to_jiffies64 - Convert nsecs in u64 to jiffies64@n: nsecs in u64 Unlike {m,u}secs_to_jiffies, type of input is not unsigned int but u64.* And this doesn't return MAX_JIFFY_OFFSET since this function is designed
ntp_update_frequency	Update (tick_length, tick_length_base, tick_nsec), based* on (tick_usec, ntp_tick_adj, time_freq):
kdb_sysinfo	Most of this code has been lifted from kernel/timer.c::sys_sysinfo().* I cannot call that code directly from kdb, it has an unconditional* cli()/sti() and calls routines that take locks which can stop the debugger.
fill_stats_for_tgid
bacct_add_tsk	ll in basic accounting fields
print_verification_stats
update_perf_cpu_limits
wb_position_ratio	Dirty position control
wb_update_dirty_ratelimit	Maintain wb->dirty_ratelimit, the base dirty throttle rate.* Normal wb tasks will be curbed at or below it in long term.* Obviously it should be around (write_bw / N) when there are N dd tasks.
wb_dirty_limits
mem_cgroup_handle_over_high	Scheduled by try_charge() to be executed from the userland return path* and reclaims memory over the high limit.
queue_wb_lat_show
blk_rq_stat_sum	src is a per-cpu stat, mean isn't initialized
last_lba	last_lba(): return number of last logical block of device@bdev: block device Description: Returns last LBA value on success, 0 on error.* This is stored (by sd and ide-geometry) in* the part[0] entry for this disk, and is the number of

tcp_time_stamp	This should only be used in contexts where tp->tcp_mstamp is up to date
tcp_ns_to_ts	Convert a nsec timestamp into TCP TSval timestamp (ms based currently)
tcp_skb_timestamp_us	provide the departure time in us unit
