Subject: [PATCH v5 03/17] perf ftrace: add option -t/--tid to filter by thread id
Date: Sat, 11 Jul 2020 20:40:21 +0800 [thread overview]
Message-ID: <20200711124035.6513-4-changbin.du@gmail.com> (raw)
In-Reply-To: <20200711124035.6513-1-changbin.du@gmail.com>
This allows us to trace single thread instead of the whole process.
