Subject: [PATCH v5 09/10] change time types to new y2038 safe __kernel_* types
Date: Tue, 13 Mar 2018 21:03:32 -0700 [thread overview]
Message-ID: <20180314040333.3291-10-deepa.kernel@gmail.com> (raw)
In-Reply-To: <20180314040333.3291-1-deepa.kernel@gmail.com>
Change over clock_settime, clock_gettime and clock_getres
syscalls to use __kernel_timespec times. This will enable
changing over of these syscalls to use new y2038 safe syscalls
when the architectures define the CONFIG_64BIT_TIME.
