Subject: [PATCH v3 00/22] Convert the posix_clock_operations and k_clock structure to ready for 2038
Date: Mon, 11 May 2015 19:08:38 +0800 [thread overview]
Message-ID: <1431342518-29362-1-git-send-email-baolin.wang@linaro.org> (raw)
This patch series changes the 32-bit time type (timespec/itimerspec) to the 64-bit one
(timespec64/itimerspec64), since 32-bit time types will break in the year 2038.
This patch series introduces new methods with timespec64/itimerspec64 type,
and removes the old ones with timespec/itimerspec type for posix_clock_operations
and k_clock structure.
Also introduces some new functions with timespec64/itimerspec64 type, like current_kernel_time64(),
hrtimer_get_res64(), cputime_to_timespec64() and timespec64_to_cputime().
Changes since v2:
-Split the syscall conversion patch into small some patches.
Baolin Wang (22):
linux/time64.h:Introduce the 'struct itimerspec64' for 64bit
timekeeping:Introduce the current_kernel_time64() function with
timespec64 type
time/hrtimer:Introduce hrtimer_get_res64() with timespec64 type for
getting the timer resolution
posix-timers:Split out the guts of the syscall and change the
implementation for timer_gettime
posix-timers:Convert to the 64bit methods for the timer_gettime
syscall function
posix-timers:Split out the guts of the syscall and change the
implementation for timer_settime
posix-timers:Convert to the 64bit methods for the timer_settime
syscall function
posix-timers:Split out the guts of the syscall and change the
implementation for clock_settime
posix-timers:Convert to the 64bit methods for the clock_settime
syscall function
posix-timers:Split out the guts of the syscall and change the
implementation for clock_gettime
posix-timers:Convert to the 64bit methods for the clock_gettime
syscall function
posix-timers:Split out the guts of the syscall and change the
implementation for clock_getres
posix-timers:Convert to the 64bit methods for the clock_getres
syscall function
time:Introduce the do_sys_settimeofday64() function with timespec64
type
time/posix-timers:Convert to the 64bit methods for k_clock callback
functions
char/mmtimer:Convert to the 64bit methods for k_clock callback
function
time/alarmtimer:Convert to the new 64bit methods for k_clock
structure
time/posix-clock:Convert to the 64bit methods for k_clock and
posix_clock_operations structure
time/time:Introduce the timespec64_to_jiffies/jiffies_to_timespec64
function
cputime:Introduce the cputime_to_timespec64/timespec64_to_cputime
function
time/posix-cpu-timers:Convert to the 64bit methods for k_clock
structure
k_clock:Remove the 32bit methods with timespec/itimerspec type
