From: frank zago <fzago@xxxxxxxx> It is preferable to use NULL instead of 0 for pointers. This fixes sparse warnings such as: lustre/fld/fld_request.c:126:17: warning: Using plain integer as NULL pointer The second parameter of class_match_param() was changed to a const, to be able to remove a cast in one user, to prevent splitting a long line. No other code change.
