+Subject: [PATCH 136/347] rtmutex: Make lock_killable work
+Origin: https://www.kernel.org/pub/linux/kernel/projects/rt/4.19/older/patches-4.19.246-rt110.tar.xz
+
+Locking an rt mutex killable does not work because signal handling is
+restricted to TASK_INTERRUPTIBLE.
+
+Use signal_pending_state() unconditionaly.
