Subject: [PATCH v4 10/10] bootconfig/tracing/ktest: Update ktest example for boot-time tracing
Date: Tue, 10 Aug 2021 11:08:22 +0900	[thread overview]
Message-ID: <162856130208.203126.4458319094852152589.stgit@devnote2> (raw)
In-Reply-To: <162856122550.203126.17607127017097781682.stgit@devnote2>

Update ktest example for the boot-time tracing with histogram
options. Note that since the histogram option uses "trace()" action
instead of "EVENT()", this updates the matching pattern too.
