Subject: [PATCH v3 10/11] NFS COPY handle ERR_OFFLOAD_DENIED
Date: Thu, 25 Oct 2018 17:51:46 -0400 [thread overview]
Message-ID: <20181025215147.36248-12-olga.kornievskaia@gmail.com> (raw)
In-Reply-To: <20181025215147.36248-1-olga.kornievskaia@gmail.com>
From: Olga Kornievskaia <kolga@netapp.com>
If server sends ERR_OFFLOAD_DENIED error, the client must fall
back on doing copy the normal way. Return ENOTSUPP to the vfs and
fallback to regular copy.
