ktime_get_real_ts64 ktime_get_real_ts64函数诞生于linux v3.17,当时是一个宏定义如下: externvoidgetnstimeofday64(structtimespec64*tv);#define ktime_get_real_ts64(ts) getnstimeofday64(ts) 在linux v5.0中,也就是do_gettimeofday正式退役时,我们看看ktime_get_real_ts64的样子。其在kernel/time/ti...
do_posix_clock_monotonic_gettime() is a leftover from the initial posix timer implementation which maps to ktime_get_ts(). Signed-off-by: Thomas Gleixner <tglx@linutronix.de> Cc: John Stultz <john.stultz@linaro.org> Cc: Peter Zijlstra <peterz@infradead.org> Cc: Jason Wessel <jason....
do_gettimeofday：定义位于arch/i386/kernel/time.c。ktime_get_real_ts64：定义位于kernel/time/timekeeping.c，声明则在include/linux/timekeeping.h。替代关系：替代背景：do_gettimeofday因32bit机器上的2038问题而被官方文档明确指出需要替代，替代函数为ktime_get_real_ts64。替代效果：ktime_get_real...

do_gettimeofday函数，自linux v0.99.9版本诞生，起初为内部inline static函数。至linux v2.0版本，正式升级为外部接口。其定义位于arch/i386/kernel/time.c。然而，随着linux v5.0的更新，do_gettimeofday退出历史舞台。原因在于struct timeval在32bit机器上面临2038问题。替代函数为ktime_get_real_ts64...
