Subject: [patch V2 5/8] posix-cpu-timers: Move inlines out of public header
Date: Sat, 05 Sep 2026 20:59:19 +0200 [thread overview]
Message-ID: <20260905185839.868259402@kernel.org> (raw)
In-Reply-To: 20260905181551.738186850@kernel.org
They are only used in the POSIX CPU timer code. No point in exposing them
globally and parsing them for nothing.
