Subject[PATCH v3 00/22] Convert the posix_clock_operations and k_clock structure to ready for 2038
Date
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.

*** BLURB HERE ***
