Subject: [patch 14/14] tasklets: Switch tasklet_disable() to the sleep wait variant
Date: Tue, 09 Mar 2021 09:42:17 +0100	[thread overview]
Message-ID: <20210309084242.726452321@linutronix.de> (raw)
In-Reply-To: 20210309084203.995862150@linutronix.de

 -- NOT FOR IMMEDIATE MERGING --

Now that all users of tasklet_disable() are invoked from sleepable context,
convert it to use tasklet_unlock_wait() which might sleep.
