            Bug ID: 244563
           Summary: vmstat -m show improbably values
           Product: Base System
           Version: CURRENT
          Hardware: Any
                OS: Any
            Status: New
          Severity: Affects Some People
          Priority: ---
         Component: kern
          Assignee: bugs at FreeBSD.org
          Reporter: swills at FreeBSD.org

Using r358506, when I run vmstat -m, I see:

vmstat -m | head -n 1 ; vmstat -m | grep temp 
         Type InUse MemUse HighUse Requests  Size(s)
         temp 18446744073709551525 18014398509481813K       - 80059557 
16,32,64,128,256,512,1024,2048,4096,8192,16384,32768,65536

I see this on both my workstation and on the package builders (those are on
r356856), but only while poudriere is building packages. Perhaps it's related
to tmpfs usage? Not sure, but the values here look wrong.
