Subject: [PATCH] blktrace: document -k option
Message-Id: <518B0355.3030905@redhat.com>
List-Id: <linux-btrace.vger.kernel.org>
MIME-Version: 1.0
Content-Type: text/plain; charset="us-ascii"
Content-Transfer-Encoding: 7bit
To: linux-btrace@vger.kernel.org

The -k option was missing from the usage() output and was present
only in the man page synopsis.  Say a few more words about it.
