[PATCH 3/8] [PATCH 3/8] tracing: Check absolute path of input file in recordmcount.pl

[Steven Rostedt]

From: Li Hong <lihong.hi@xxxxxxxxx>

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.
