Subject: [PATCH v1 20/22] SUNRPC: Clean up RPC scheduler tracepoints
Date: Wed, 08 Jul 2020 16:10:45 -0400 [thread overview]
Message-ID: <20200708201045.22129.93054.stgit@manet.1015granger.net> (raw)
In-Reply-To: <20200708200121.22129.92375.stgit@manet.1015granger.net>
Remove several redundant dprintk call sites, and replace a couple of
potentially useful ones with tracepoints.
