Subject: [patch V3 5/8] posix-cpu-timers: Move inlines out of public header
Date: Fri, 11 Sep 2026 11:09:31 +0200	[thread overview]
Message-ID: <20260911090541.785749315@kernel.org> (raw)
In-Reply-To: 20260911090341.949101445@kernel.org

From: Thomas Gleixner <tglx@kernel.org>

They are only used in the POSIX CPU timer code. No point in exposing them
globally and parsing them for nothing.
