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

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

[Baolin Wang]

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.

I have two more very general comments about the series:

a) something has gone wrong with your submission in v2 and v3 but was
   working earlier: normally all emails should be sent by git-send-email
   as replies to the [patch 00/22] mail. This is the default, and it
   is enabled by the '--thread --no-chain-reply' options. Please try
   to get this to work again.

b) it would be better to have a little shorter subject lines, to avoid
   line-wrapping in the list above. Here are some examples what you could
   use to replace the lines above:

   timekeeping: introduce struct itimerspec64
   timekeeping: introduce current_kernel_time64()
   hrtimer: introduce hrtimer_get_res64() 
   posix-timers: split up sys_timer_gettime()
   posix-timers: convert timer_gettime() to timespec64

   In general, try to come up with the shortest description that
   uniquely describes what your patch does, and move any details into
   the longer patch description.

OK, i'll fix these in next patch series.Thanks for your comments.

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.
