From 3537ecb49cf7177274607004c562d6f9ecc99474 Mon Sep 17 00:00:00 2001 From: Adhemerval Zanella Date: Tue, 5 Nov 2019 21:37:44 +0000 Subject: Refactor nanosleep in terms of clock_nanosleep The generic version is straightforward. For Hurd, its nanosleep implementation is moved to clock_nanosleep with adjustments from generic unix implementation. The generic clock_nanosleep unix version is also removed since it calls nanosleep. Checked on x86_64-linux-gnu and powerpc64le-linux-gnu.
