Subject: [RFC PATCH 2/6] NFSD: Remove a never-true comparison
Date: Thu, 17 Oct 2024 11:03:52 -0400	[thread overview]
Message-ID: <20241017150349.216096-10-cel@kernel.org> (raw)
In-Reply-To: <20241017150349.216096-8-cel@kernel.org>

From: Chuck Lever <chuck.lever@oracle.com>

fh_size is an unsigned int, thus it can never be less than 0.

Fixes: d8b26071e65e ("NFSD: simplify struct nfsfh")
