Subject: [PATCH v3 5/5] trace: events: rcu: Change description of rcu_dyntick trace event
Date: Mon, 4 May 2020 08:05:05 -0400 [thread overview]
Message-ID: <20200504120505.89351-6-joel@joelfernandes.org> (raw)
In-Reply-To: <20200504120505.89351-1-joel@joelfernandes.org>
From: Madhuparna Bhowmik <madhuparnabhowmik10@gmail.com>
The different strings used for describing the polarity are
Start, End and StillNonIdle. Since StillIdle is not used in any trace
point for rcu_dyntick, it can be removed and StillNonIdle can be added
in the description. Because StillNonIdle is used in a few tracepoints for
rcu_dyntick.
Similarly, USER, IDLE and IRQ are used for describing context in
the rcu_dyntick tracepoints. Since, "KERNEL" is not used for any
of the rcu_dyntick tracepoints, remove it from the description.
