From 3cb8bc6ac95ff86147d11ee1d36d18e1ddf3637c Mon Sep 17 00:00:00 2001 From: Masami Hiramatsu Date: Thu, 25 Feb 2010 08:35:27 -0500 Subject: perf probe: Fix bugs in line range finder Fix find_line_range_by_line() to init line_list and remove misconseptional found marking which should be done when real lines are found (if there is no lines probe-able, find_line_range() should return 0).
