Subject: [PATCH 6.12.y 2/5] nfsd: Drop dprintk in blocklayout xdr functions
Date: Mon, 20 Oct 2025 16:33:40 -0400	[thread overview]
Message-ID: <20251020203343.1907954-2-sashal@kernel.org> (raw)
In-Reply-To: <20251020203343.1907954-1-sashal@kernel.org>

From: Sergey Bashirov <sergeybashirov@gmail.com>

[ Upstream commit e339967eecf1305557f7c697e1bc10b5cc495454 ]

Minor clean up. Instead of dprintk there are appropriate error codes.
