1.109 + * We don't try to hide the difference by leaving out the args because

1.113 + *
1.114 + * The kernel should reverse the cast before calling the function. It
1.115 + * has no way to do this, but on most machines 1-arg and 3-arg functions
1.116 + * have the same calling protocol so there is no problem in practice.
1.117 + * A bit in sa_flags could be used to specify the number of args.
