From 24fc43821f54c5f95095fb5154422b54ba2777e2 Mon Sep 17 00:00:00 2001
From: Thomas Gleixner <tglx@linutronix.de>
Date: Tue, 9 Mar 2021 09:42:17 +0100
Subject: [PATCH 145/323] tasklets: Switch tasklet_disable() to the sleep wait
variant
Origin: https://www.kernel.org/pub/linux/kernel/projects/rt/5.10/older/patches-5.10.204-rt100.tar.xz
-- 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.
