Subject: [PATCH v3 01/15] nfsd: rq_lease_breaker cleanup
Date: Thu, 01 Oct 2020 18:58:51 -0400	[thread overview]
Message-ID: <160159313183.79253.5459981038625192952.stgit@klimt.1015granger.net> (raw)
In-Reply-To: <160159301676.79253.16488984581431975601.stgit@klimt.1015granger.net>

From: J. Bruce Fields <bfields@redhat.com>

Since only the v4 code cares about it, maybe it's better to leave
rq_lease_breaker out of the common dispatch code?
