Subject: [patch 5/8] posix-cpu-timers: Move inlines out of public header
Date: Fri, 04 Sep 2026 13:22:40 +0200 [thread overview]
Message-ID: <20260904112202.297869969@kernel.org> (raw)
In-Reply-To: <20260904112100.683893401@kernel.org>
They are only used in the POSIX CPU timer code. No point in exposing them
globally and parsing them for nothing.
