Subject: [PATCH v5 21/30] xprtrdma: Add trace points for calls to transport switch methods
Date: Wed, 19 Dec 2018 11:00:00 -0500 [thread overview]
Message-ID: <20181219160000.11602.77153.stgit@manet.1015granger.net> (raw)
In-Reply-To: <20181219155152.11602.18605.stgit@manet.1015granger.net>
Name them "trace_xprtrdma_op_*" so they can be easily enabled as a
group. No trace point is added where the generic layer already has
observability.
