1: s/suser/suser_xxx/ 2: Add new function: suser(struct proc *), prototyped in <sys/proc.h>. 3: s/suser_xxx(\([a-zA-Z0-9_]*\)->p_ucred, \&\1->p_acflag)/suser(\1)/ The remaining suser_xxx() calls will be scrutinized and dealt with later. There may be some unneeded #include <sys/cred.h>, but they are left as an exercise for Bruce. More changes to the suser() API will come along with the "jail" code.
