From d56728b8d7fb3e1e5e5f97b88fdf6b43a35b4f5e Mon Sep 17 00:00:00 2001 From: Juha Leppanen Date: Mon, 7 Dec 2009 12:00:40 -0500 Subject: perf probe: Fix strtailcmp() to compare s1and s2[0] Fix strtailcmp() to compare s1[0] and s2[0]. strtailcmp() returns 0 if "a" and "b" or "a" and "ab", it's a wrong behavior. This patch fixes it.
