From 6b61c969d501ad5ae035d27b75fa6c7f2eb6a54a Mon Sep 17 00:00:00 2001 From: Olga Kornievskaia Date: Tue, 26 Sep 2017 13:51:39 -0400 Subject: NFS: COPY handle ERR_OFFLOAD_DENIED 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.
