From d835cb4af7f6dd0251d44490dbd581625aa634d7 Mon Sep 17 00:00:00 2001 From: Thomas Gleixner Date: Tue, 14 Jul 2015 14:26:34 +0200 Subject: [PATCH 118/352] panic: skip get_random_bytes for RT_FULL in init_oops_id Disable on -RT. If this is invoked from irq-context we will have problems to acquire the sleeping lock.
