Right, thanks. Patch udpated. I've tried if this can be caught by
'-Wunused-but-set-variable', strangely only max_nr is reported:

fs/btrfs/extent_io.c: In function ‘__extent_writepage_io’:
fs/btrfs/extent_io.c:3368:17: warning: variable ‘max_nr’ set but not used [-Wunused-but-set-variable]
   unsigned long max_nr;
