    The field you refer to does not exist under -CURRENT's vmstat(8) command.

    However, the attached patch should work for you. The bug is caused by
    a signed integer and printf format being used for the statistic in question,
    totreq. This is just a running total of what the vmstat(8) command is able
    to learn from vm_meter.c's exported sysctls.

    This is a fairly quick patch but you'll need to apply it from within
    /usr/src/usr.bin/vmstat, then run a make obj/make/make install.

    I've raised a PR on your behalf with the patch enclosed, it should reach
    GNATS any second.
