From fece98260f31292dd468925c7582065bf6193212 Mon Sep 17 00:00:00 2001 From: "Eric W. Biederman" Date: Mon, 27 Apr 2020 09:38:29 -0500 Subject: [PATCH] posix-cpu-timers: Replace cpu_timer_pid_type with clock_pid_type Taking a clock and returning a pid_type is a more general and a superset of taking a timer and returning a pid_type. Perform this generalization so that future changes may use this code on clocks as well as timers. Signed-off-by: "Eric W.
