markj c52fe71eb0 uma: Make uma_zone_set_maxcache() work better with small limits ... The old implementation chose the largest bucket zone such that if the per-CPU caches are fully populated, the total number of items cached is no larger than the specified limit. If no such zone existed, UMA would not do any caching. We can now use uz_bucket_size_max to set a precise limit on the number of items in a zone's bucket, so the total size of per-CPU caches can be bounded more easily. Implement a new policy in uma_zone_set_maxcache(): choose a bucket size such that up to half of the limit can be cached in per-CPU caches, with the rest going to the full bucket cache. This fixes a problem with the kstack_cache zone: the limit of 4 * mp_ncpus items meant that the zone would not do any caching, defeating the whole purpose of the zone. That's because the smallest bucket size holds up to 2 items and we may cache up to 3 full buckets per CPU, and 2 * 3 * mp_ncpus > 4 * mp_ncpus.
