Is there a way to increase the memory size that is allocated by the kernel
to a certain kernel memory pool (is that the correct word?):
I mean, I have
options VM_KMEM_SIZE="(64*1024*1024)"
in my kernel config file, and it appears that I'm only allowed to use half
of that memory for a certain pool:
# vmstat -m | grep Filter
16 uc_devlist, p1003.1b, IP Filter, igmp, routetbl, ether_multi, vnodes,
256 file desc, FFS node, newblk, IP Filter, routetbl, ifaddr, vnodes,
512 uc_devlist, UFS mount, IP Filter, mount, BIO buffer, ptys, msg,
32K VM pgdata, UFS ihash, inodedep, IP Filter, devbuf
IP Filter 276 158K 23307K 32768K 47735 0 0 16,256,512,32K
Howerver, this box is a dedicated traffic filtering box, and I want to increase
the available kernel memory for this kmalloc category. I grepped in the
source, but apart from the assignment
type->ks_limit = vm_kmem_size / 2;
in kern_malloc.c, I could not find a place were this limit is increased.
Is it possible to circumvent this?

BTW: I'm running FreeBSD 4.3
