Subject: [PATCH 0/1] Client optimize away CB_RECALL for write delegation
Date: Thu, 28 May 2026 15:22:41 -0400 [thread overview]
Message-ID: <cover.1779995818.git.bcodding@hammerspace.com> (raw)
A client holding a write delegation that performs a SETATTR that would
remove the client's write access can expect the server to recall that
delegation. The following patch addresses the simplest case to dectect this
and then preemptively return the delegation rather than have server recall
it.
