From bdd3b052c63b2c19a0118937f500985c01a19956 Mon Sep 17 00:00:00 2001 From: Li Hong Date: Wed, 28 Oct 2009 13:03:32 +0800 Subject: tracing: Check absolute path of input file in recordmcount.pl The ftrace.c file may reference the mcount function and this may interfere with the recordmcount.pl processing. To avoid this, the code does not process the kernel/trace/ftrace.o. But currently the check is against a relative path. This patch modifies the check to succeed if the path is an absolute path.
