Subject: [PATCH pynfs v2 01/25] nfs4.1: add proposed NOTIFY4_GFLAG_EXTEND flag
Date: Thu, 16 Apr 2026 11:14:33 -0700 [thread overview]
Message-ID: <20260416-dir-deleg-v2-1-fad510db5941@kernel.org> (raw)
In-Reply-To: <20260416-dir-deleg-v2-0-fad510db5941@kernel.org>
This flag has been proposed as part of RFC8881bis. This flag is used to
negotiate extensions to the original directory delegations originally
specified in RFC8881.
In practice, the Linux nfs server requires that the client support this
flag if it's requesting anything other than a recall-only delegation.
