From c7f5194054e103d18d267385b866b5b90511a425 Mon Sep 17 00:00:00 2001 From: "Eric W. Biederman" Date: Tue, 28 Apr 2020 13:00:39 -0500 Subject: posix-cpu-timer: Unify the now redundant code in lookup_task Now that both !thread paths through lookup_task call thread_group_leader, unify them into the single test at the end of lookup_task. This unification just makes it clear what is happening in the gettime special case of lookup_task. Signed-off-by: "Eric W.
