Subject: [RFC PATCH 5/6] NFSD: Remove unused values from nfsd4_encode_components_esc()
Date: Thu, 17 Oct 2024 11:03:55 -0400 [thread overview]
Message-ID: <20241017150349.216096-13-cel@kernel.org> (raw)
In-Reply-To: <20241017150349.216096-8-cel@kernel.org>
From: Chuck Lever <chuck.lever@oracle.com>
Clean up. The computed value of @p is saved each time through the
loop but is never used.
