From 5c542368a3ded88bed98239fb3570dda416203ee Mon Sep 17 00:00:00 2001 From: Arnaud Patard Date: Fri, 19 Sep 2008 20:16:25 -0700 Subject: tracing/fastboot: fix bootgraph.pl initcall name regexp The regexp used to match the start and the end of an initcall are matching only on [a-zA-Z\_]. This rules out initcalls with a number in them. This patch is fixing that.
