Subject: [PATCH RFC 10/21] NFSD: Replace the nfsd_deleg_break tracepoint
Date: Mon, 10 May 2021 11:52:39 -0400	[thread overview]
Message-ID: <162066195924.94415.4581490923389520515.stgit@klimt.1015granger.net> (raw)
In-Reply-To: <162066179690.94415.203187037032448300.stgit@klimt.1015granger.net>

Renamed so it can be enabled as a set with the other nfsd_cb_
tracepoints. And, consistent with those tracepoints, report the
address of the client, the client ID the server has given it, and
the state ID being recalled.
