Subject: [patch V5 22/72] locking/rtmutex: Use rt_mutex_wake_q_head
Date: Sun, 15 Aug 2021 23:28:09 +0200 (CEST)	[thread overview]
Message-ID: <20210815211303.197113263@linutronix.de> (raw)
In-Reply-To: <20210815203225.710392609@linutronix.de>

From: Thomas Gleixner <tglx@linutronix.de>

Prepare for the required state aware handling of waiter wakeups via wake_q
and switch the rtmutex code over to the rtmutex specific wrapper.

No functional change.
