Subject: [PATCH 06/14] locking: add lockevent_read() prototype
Date: Wed, 17 May 2023 15:10:54 +0200 [thread overview]
Message-ID: <20230517131102.934196-7-arnd@kernel.org> (raw)
In-Reply-To: <20230517131102.934196-1-arnd@kernel.org>
From: Arnd Bergmann <arnd@arndb•de>
lockevent_read() has a __weak definition and the only caller in
kernel/locking/lock_events.c, plus a strong definition in qspinlock_stat.h
that overrides it, but no other declaration. This causes a W=1
warning:
kernel/locking/lock_events.c:61:16: error: no previous prototype for 'lockevent_read' [-Werror=missing-prototypes]
Add shared prototype to avoid the warnings.
Signed-off-by: Arnd Bergmann <arnd@arndb•de>
