From bf5d770bd234a1e66322dd79c4ae5b397cd2b9c1 Mon Sep 17 00:00:00 2001 From: Steven Rostedt Date: Wed, 1 May 2013 13:35:51 -0400 Subject: [PATCH] init: Do not warn on non-zero initcall return Commit f91eb62f71b3 ("init: scream bloody murder if interrupts are enabled too early") added three new warnings. The first two seemed reasonable, but the third included a warning when an initcall returned non-zero. Although, the third WARN() does include an imbalanced preempt disabled, or irqs disable, it shouldn't warn if it only had an initcall that just returns non-zero. In fact, according to Linus, it shouldn't print at all. As it only prints with initcall_debug set, and that already shows enough information to fix things.
