Thanks for reporting it. I just sent out a > series fixing this issue, you are on Cc: I think this should also be fixed by the patch I've sent: (74946415a "fs: Fix link_path_walk to return -ENOENT on empty path") This patch might not have fixed this exact case when running the nfs command. Have you been able to repoduce this issue with this patch applied ? I've havn't tried to setup a net interface to debug nfs commandi, instead I was using simpler command such as `md5sum ""`.
