Subject: [PATCH v2 10/14] linux: Add time64 support for nanosleep
Date: Tue, 8 Sep 2020 11:57:34 -0300 [thread overview]
Message-ID: <20200908145738.640039-10-adhemerval.zanella@linaro.org> (raw)
In-Reply-To: <20200908145738.640039-1-adhemerval.zanella@linaro.org>
It uses __clock_nanosleep64 and adds the __nanosleep64 symbol.
Checked on x86_64-linux-gnu and i686-linux-gnu (on 5.4 and on 4.15
kernel).
