From 5cd2b459d326a424671dcd95f038649f7bf7cb96 Mon Sep 17 00:00:00 2001 From: Arjan van de Ven Date: Fri, 25 Jul 2008 19:45:39 -0700 Subject: [PATCH] Use WARN() in lib/ Use WARN() instead of a printk+WARN_ON() pair; this way the message becomes part of the warning section for better reporting/collection. In addition, one of the if() clauses collapes into the WARN() entirely now.
