From a8f2a68e42d19e6fc1e0eb6eaef548ef07b19d75 Mon Sep 17 00:00:00 2001 From: Gao Xiang Date: Wed, 10 Mar 2021 03:15:50 +0800 Subject: [PATCH] Documentation: sysrq: update description about sysrq crash After commit 8341f2f222d7 ("sysrq: Use panic() to force a crash"), a crash was not generated by dereferencing a NULL pointer anymore. Let's update documentation as well to make it less misleading.
