Subject: [PATCH] NFSv4.2: Add special handling for LISTXATTR receiving NFS4ERR_NOXATTR
Date: Wed, 21 Sep 2022 13:24:40 -0400 [thread overview]
Message-ID: <20220921172440.158049-1-anna@kernel.org> (raw)
From: Anna Schumaker <Anna.Schumaker@Netapp.com>
We can translate this into an empty response list instead of passing an
error up to userspace.
