sys/kern kern_acct.c
Log:
Provide some anti-footshooting. Don't allow the user to set the interval
for acctwatch() runs to be negative or zero as this could result in either
a possible hang (or panic if INVARIANTS is on). Previously the accounting
code handled the <= 0 case by calling acctwatch on every clock tick (eww!)
due to an implementation detail of callout_reset(). (Tick counts of
<= 0 are converted to 1).
