Signed-off-by: Xunlei Pang <pang.xunlei@...aro.org> --- read_persistent_clock() and update_persistent_clock() are way more complex, so we will deal with them gradually in extra patchsets. include/linux/timekeeping.h | 1 - kernel/time/timekeeping.c | 14 +++----------- 2 files changed, 3 insertions(+), 12 deletions(-) diff --git a/include/linux/timekeeping.h b/include/linux/timekeeping.h index a7fa96b..72631e8 100644 --- a/include/linux/timekeeping.h +++ b/include/linux/timekeeping.h @@ -263,7 +263,6 @@ static inline bool has_persistent_clock(void) extern void read_persistent_clock(struct timespec *ts); extern void read_persistent_clock64(struct timespec64 *ts); -extern void read_boot_clock(struct timespec *ts); extern void read_boot_clock64(struct timespec64 *ts); extern int update_persistent_clock(struct timespec now); extern int update_persistent_clock64(struct timespec64 now); diff --git a/kernel/time/timekeeping.c b/kernel/time/timekeeping.c index 0e5a696..d0ca908 100644 --- a/kernel/time/timekeeping.c +++ b/kernel/time/timekeeping.c @@ -1066,28 +1066,20 @@ void __weak read_persistent_clock64(struct timespec64 *ts64) } /** - * read_boot_clock - Return time of the system start. + * read_boot_clock64 - Return time of the system start. * * Weak dummy function for arches that do not yet support it. * Function to read the exact time the system has been started. - * Returns a timespec with tv_sec=0 and tv_nsec=0 if unsupported. + * Returns a timespec64 with tv_sec=0 and tv_nsec=0 if unsupported. * * XXX - Do be sure to remove it once all arches implement it. */ -void __weak read_boot_clock(struct timespec *ts) +void __weak read_boot_clock64(struct timespec64 *ts) { ts->tv_sec = 0; ts->tv_nsec = 0; } -void __weak read_boot_clock64(struct timespec64 *ts64) -{ - struct timespec ts; - - read_boot_clock(&ts); - *ts64 = timespec_to_timespec64(ts); -} - /* * timekeeping_init - Initializes the clocksource and common timekeeping values */ -- 1.9.1 -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@...r.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
