- Mark internal routines as static; - Eliminate unused parameters where possible, mark __unused for others; - Remove unused variables; - Use %jd for int64_t values in printf(); - Add appropriate %d for printf to match its parameter; - Rename a variable to resolve conflict with revoke(2); Reviewed by: rmacklem Tested with: make universe (bugs are mine)
