CIFS: make 'nodfs' mount opt a superblock flag
tcon->Flags is only used by SMB1 code and changing it is not permanent (you lose the setting on tcon reconnect). * Move the setting to superblock flags (per mount-points). * Make automount callback exit early when flag present * Make dfs resolving happening in mount syscall exit early if flag present Signed-off-by: Aurelien Aptel <aaptel@suse.com> Signed-off-by: Steve French <stfrench@microsoft.com> Acked-by: Pavel Shilovsky <pshilov@microsoft.com>
