Subject: [patch 2/3] timekeeping: Mark tk_clock_read() __always_inline
Date: Fri, 15 Apr 2022 11:19:36 +0200 (CEST) [thread overview]
Message-ID: <20220415091921.014937522@linutronix.de> (raw)
In-Reply-To: 20220415091223.187169221@linutronix.de
Compilers can uninline this which makes the notrace annotation of the NMI
safe accessors moot.
