Subject: panic: skip get_random_bytes for RT_FULL in init_oops_id
From: Thomas Gleixner <tglx@linutronix.de>
Date: Tue Jul 14 14:26:34 2015 +0200
Origin: https://www.kernel.org/pub/linux/kernel/projects/rt/5.15/older/patches-5.15.3-rt21.tar.xz
From: Thomas Gleixner <tglx@linutronix.de>
Disable on -RT. If this is invoked from irq-context we will have problems
to acquire the sleeping lock.
