From 724e7bfcc566375158219c1454b4b6fc416b2c4a Mon Sep 17 00:00:00 2001 From: Pranith Kumar Date: Wed, 11 Mar 2015 14:08:19 -0400 Subject: [PATCH] audit: Remove condition which always evaluates to false MIME-Version: 1.0 Content-Type: text/plain; charset=utf8 Content-Transfer-Encoding: 8bit After commit 3e1d0bb6224f019893d1c498cc3327559d183674 ("audit: Convert int limit uses to u32"), by converting an int to u32, few conditions will always evaluate to false. These warnings were emitted during compilation: kernel/audit.c: In function ‘audit_set_enabled’: kernel/audit.c:347:2: warning: comparison of unsigned expression < 0 is always false [-Wtype-limits] if (state < AUDIT_OFF || state > AUDIT_LOCKED) ^ kernel/audit.c: In function ‘audit_receive_msg’: kernel/audit.c:880:9: warning: comparison of unsigned expression < 0 is always false [-Wtype-limits] if (s.backlog_wait_time < 0 || The following patch removes those unnecessary conditions.
