Subject: [PATCH 1/2] x86/percpu: Rename percpu_stable_op() to __raw_cpu_read_stable()
Date: Mon, 20 May 2024 10:09:24 +0200	[thread overview]
Message-ID: <20240520080951.121049-1-ubizjak@gmail.com> (raw)

Rename percpu_stable_op() to __raw_cpu_read_stable() to be
in line with other read/write percpu accessors.

No functional change intended.
