jhb 2006-02-07 18:59:47 UTC FreeBSD src repository Modified files: 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). MFC after: 3 days Revision Changes Path 1.80 +23 -2 src/sys/kern/kern_acct.c
