-Subject: [PATCH] arm: kprobe: replace patch_lock to raw lock
-Origin: https://www.kernel.org/pub/linux/kernel/projects/rt/5.0/older/patches-5.0.7-rt5.tar.xz
-
-When running kprobe on -rt kernel, the below bug is caught:
-
-BUG: sleeping function called from invalid context at kernel/locking/rtmutex.c:931
-in_atomic(): 1, irqs_disabled(): 128, pid: 14, name: migration/0
-INFO: lockdep is turned off.

-
-Since patch_text_stop_machine() is called in stop_machine() which disables IRQ,
-sleepable lock should be not used in this atomic context, so replace patch_lock
-to raw lock.
