Subject: [PATCH v2 08/21] nfsd: remove premature NFS4_OO_CONFIRMED in CLAIM_PREVIOUS path
Date: Thu, 11 Jun 2026 16:00:51 -0400	[thread overview]
Message-ID: <20260611-nfsd-testing-v2-8-5b90e276f2d9@kernel.org> (raw)
In-Reply-To: <20260611-nfsd-testing-v2-0-5b90e276f2d9@kernel.org>

nfsd4_open() sets NFS4_OO_CONFIRMED on the openowner before calling
do_open_fhandle(), which can fail. If it fails, the openowner stays
permanently confirmed despite the OPEN failing. The correct
success-path setter already exists in init_open_stateid().

Remove the premature setter. NFSv4.1+ is unaffected as sessions
always confirm at creation time.

Fixes: a525825df152 ("[PATCH] nfsd4: handle replays of failed open reclaims")
Assisted-by: Claude:claude-opus-4-8
