vfs: cleanup show_mountinfo
Starting with commit v3.2-rc4-1-g02125a8, seq_path_root() no longer changes the value of its "struct path *root" argument. Starting with commit v3.2-rc7-104-g8c9379e, the "struct path *root" argument of seq_path_root() is const. As result, the temporary variable "root" in show_mountinfo() that holds a copy of struct path root is no longer needed. Signed-off-by: Dmitry V. Levin <ldv@altlinux.org> Signed-off-by: Al Viro <viro@zeniv.linux.org.uk>
