src/sys/netsmb [netbsd-4-0]: subr_mchain.c
Pull up following revision(s) (requested by nakayama in ticket #1445):
sys/netsmb/subr_mchain.c: revision 1.21
Since "len" has changed to (unsinged) size_t, the while loop
condition (len > 0) became less able to detect its underflow.
So check the subtrahend to avoid the underflow.
Should fix PR kern/44092.
