Subject: [BUGFIX PATCH -tip 2/5] perf probe: Fix strtailcmp() to compare s1[0] and s2[0]
Date: Mon, 07 Dec 2009 16:56:00 -0000 [thread overview]
Message-ID: <20091207170040.19230.37464.stgit@dhcp-100-2-132.bos.redhat.com> (raw)
In-Reply-To: <20091207170027.19230.39491.stgit@dhcp-100-2-132.bos.redhat.com>
From: Juha Leppanen <juha_motorsportcom@luukku.com>
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.
