Subject: [patch 37/50] locking/mutex: Rearrange items in mutex.h
Date: Tue, 13 Jul 2021 17:11:31 +0200 [thread overview]
Message-ID: <20210713160749.555316784@linutronix.de> (raw)
In-Reply-To: 20210713151054.700719949@linutronix.de
From: Thomas Gleixner <tglx@linutronix.de>
Move the lockdep map initializer to a different place so it can be shared
with the upcoming RT variant of struct mutex.
No functional change.
