Re: systat -vm output showing negative total virtual memory

Actually, the values are also in pages. Below is a new patch

insane; I think some objects are included in the stats
mistakenly, but I'm not yet sure.

Okay, the attached patch that includes a "fix" for vm_meter.c
now prints the sane values for virtual memory. The huge
contributions to vm total were from vnode objects representing
mounted file systems (g_vfs_open()).

Alan, could you please review this patch for me (the vm_meter.c
portion at least) or suggest a better fix? On my amd64 system,
I now get:

: vm.vmtotal:
: System wide totals computed every five seconds: (values in kilobytes)
: ===============================================
: Processes: (RUNQ: 2 Disk Wait: 0 Page Wait: 0 Sleep: 35)
: Virtual Memory: (Total: 4458372K, Active 95772K)
: Real Memory: (Total: 93468K Active 71016K)
: Shared Virtual Memory: (Total: 20504K Active: 18952K)
: Shared Real Memory: (Total: 13956K Active: 13148K)
: Free Memory Pages: 3024836K

The patch is against RELENG_6 but should apply to HEAD too.
