Subject: [PATCH -tip 08/14] perf probe: Use strlist__for_each macros in 	probe-event.c
Date: Tue, 15 Dec 2009 15:27:00 -0000	[thread overview]
Message-ID: <20091215153203.17436.52039.stgit@dhcp-100-2-132.bos.redhat.com> (raw)
In-Reply-To: <20091215153106.17436.66584.stgit@dhcp-100-2-132.bos.redhat.com>

Use strlist__for_each macros instead of using strlist__entry()
and index variable.
