Re: objcache depot not used?
Oh, we probably want to change that calculation to free at least a few
items to backing store, rather then cache to the limit.
n = 0;
if (cluster_limit > 0) {
n = (cluster_limit - ncpus * 2 * mag_capacity) / mag_capacity;
n >>= 1; /* retain at most 50% of the limit */
/* can be negative */
}
if (n < 2) /* minimum, also handles unlimited case */
n = 2;
if (n > 10) /* don't go overboard */
n = 10;
