Name:div_u64 - unsigned 64bit divide with 32bit divisor*@dividend: unsigned 64bit dividend*@divisor: unsigned 32bit divisor* This is the most common 64bit divide and should be used if possible,* as many 32bit archs can optimize this variant better than a full

Proto:static inline u64 div_u64(u64 dividend, u32 divisor)

Type:u64

Parameter:

NameDescribe
vsscanfvsscanf - Unformat a buffer into a list of arguments*@buf: input buffer*@fmt: format of buffer*@args: arguments
_parse_integerConvert 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_remdiv64_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_u64div64_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_normalizeM2Secondary normalization method.To be used when primary method fails.

scale_stimePerform (stime * rtime) / total, but avoid multiplication overflow by* losing precision when the numbers are big.

nsec_to_clock_t
nsecs_to_jiffies64secs_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_frequencyUpdate (tick_length, tick_length_base, tick_nsec), based* on (tick_usec, ntp_tick_adj, time_freq):
kdb_sysinfoMost 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.

print_verification_stats
update_perf_cpu_limits
wb_position_ratioDirty position control
wb_update_dirty_ratelimitMaintain 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_highScheduled 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_sumsrc is a per-cpu stat, mean isn't initialized
last_lbalast_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
