From e0a748983b07205d9f2f52230c897f49a2c84c8d Mon Sep 17 00:00:00 2001 From: Thomas Gleixner Date: Tue, 14 Jul 2015 14:26:34 +0200 Subject: [PATCH 243/323] panic: skip get_random_bytes for RT_FULL in init_oops_id Origin: https://www.kernel.org/pub/linux/kernel/projects/rt/5.10/older/patches-5.10.204-rt100.tar.xz Disable on -RT. If this is invoked from irq-context we will have problems to acquire the sleeping lock.
