[PATCH v4 00/25] Convert the posix_clock_operations and k_clock structure to ready for 2038

From: Baolin Wang
Date: Mon Jun 01 2015 - 07:45:39 EST


This patch series changes the 32-bit time types (timespec/itimerspec) to
the 64-bit types (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.

Baolin Wang (25):
time:Introduce struct itimerspec64
timekeeping:Introduce the current_kernel_time64()
hrtimer:Introduce hrtimer_get_res64()
security: Introduce security_settime64()
time:Introduce the do_sys_settimeofday64()
posix-timers:Introduce {get,put}_timespec/{get,put}_itimerspec
posix-timers: Split up timer_gettime()/timer_settime()/clock_settime()/
clock_gettime()/clock_getres().
posix-timers: Convert timer_gettime()/timer_settime()/clock_settime()/
clock_gettime()/clock_getres() to timespec64/itimerspec64.
mmtimer:Convert to timespec64/itimerspec64
alarmtimer:Convert to timespec64/itimerspec64
posix-clock:Convert to timespec64/itimerspec64
time:Introduce timespec64_to_jiffies()/jiffies_to_timespec64()
cputime:Introduce cputime_to_timespec64()/timespec64_to_cputime()
posix-cpu-timers:Convert to timespec64/itimerspec64
k_clock:Remove timespec/itimerspec
