cifs: Unset CIFS_MOUNT_POSIX_PATHS flag when following dfs mounts
In a dfs setup where the client transitions from a server which supports posix paths to a server which doesn't support posix paths, the flag CIFS_MOUNT_POSIX_PATHS is not reset. This leads to the wrong directory separator being used causing smb commands to fail. Consider the following case where a dfs share on a samba server points to a share on windows smb server. # mount -t cifs -o .. //vm140-31/dfsroot/testwin/ # ls -l /mnt; touch /mnt/a total 0 touch: cannot touch ‘/mnt/a’: No such file or directory Signed-off-by: Sachin Prabhu <sprabhu@redhat.com> Acked-by: Jeff Layton <jlayton@samba.org> Signed-off-by: Steve French <steve.french@primarydata.com>
