Matthew Dillon 2f9e4e8025 Limit the amount of KVM reserved for the buffer cache and for swap-meta ... information. The default limits only effect machines with > 1GB of ram and can be overriden with two new kernel conf variables VM_SWZONE_SIZE_MAX and VM_BCACHE_SIZE_MAX, or with loader variables kern.maxswzone and kern.maxbcache. This has the effect of leaving more KVM available for sizing NMBCLUSTERS and 'maxusers' and should avoid tripups where a sysad adds memory to a machine and then sees the kernel panic on boot due to running out of KVM. Also change the default swap-meta auto-sizing calculation to allocate half of what it was previously allocating. The prior defaults were way too high. Note that we cannot afford to run out of swap-meta structures so we still stay somewhat conservative here.		2001-08-20 00:41:12 +00:00
