Subject: [PATCH 1/8] nfsd: don't restart v4.1+ callback when RPC_SIGNALLED is set
Date: Thu, 23 Jan 2025 15:25:18 -0500	[thread overview]
Message-ID: <20250123-nfsd-6-14-v1-1-c1137a4fa2ae@kernel.org> (raw)
In-Reply-To: <20250123-nfsd-6-14-v1-0-c1137a4fa2ae@kernel.org>

This is problematic, since the RPC might have been entirely successful.
There is no point in restarting a v4.1+ callback just because
RPC_SIGNALLED is true. The v4.1+ error handling has other mechanisms for
detecting when it should retransmit the RPC.

Fixes: 7ba6cad6c88f ("nfsd: New helper nfsd4_cb_sequence_done() for processing more cb errors")
