Subject: [for-next][PATCH 17/19] bootconfig/tracing/ktest: Update ktest example for boot-time tracing
Date: Tue, 17 Aug 2021 15:42:24 -0400 [thread overview]
Message-ID: <20210817194305.742530204@goodmis.org> (raw)
In-Reply-To: 20210817194207.947725935@goodmis.org
From: Masami Hiramatsu <mhiramat@kernel.org>
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.
