Subject: [PATCH v3 4/4] cpumask: Update cpumask_next_wrap() signature
Date: Sun, 5 Jun 2022 08:22:41 +0200 [thread overview]
Message-ID: <52c0f58d879f9f12fc2a9230ee08da219dc5298c.1654410109.git.sander@svanheule.net> (raw)
In-Reply-To: <cover.1654410109.git.sander@svanheule.net>
The extern specifier is not needed for this declaration, so drop it. The
function also depends only on the input parameters, and has no side
effects, so it can be marked __pure like other functions in cpumask.h
