+Subject: [PATCH 317/347] sched: migrate_enable: Remove __schedule() call
+Origin: https://www.kernel.org/pub/linux/kernel/projects/rt/4.19/older/patches-4.19.246-rt110.tar.xz
+
+[ Upstream commit b8162e61e9a33bd1de6452eb838fbf50a93ddd9a ]
+
+We can rely on preempt_enable() to schedule.  Besides simplifying the
+code, this potentially allows sequences such as the following to be
+permitted:
+
+migrate_disable();
+preempt_disable();
+migrate_enable();
+preempt_enable();
