Subject: [PATCH -tip v2 5/9] [BUGFIX] perf probe: Warn when more than one line are given
Date: Thu, 11 Aug 2011 20:02:53 +0900	[thread overview]
Message-ID: <20110811110253.19900.96192.stgit@fedora15> (raw)
In-Reply-To: <20110811110220.19900.54963.stgit@fedora15>

Check multiple --lines option and print warning which
warns only the first specified --line option is valid.

Changes from the 1st post:
- Accept only the first option instead of the last.
- Fix warning message according to David's comment.
- Mark as a bugfix.
