--- Comment #3 from Scott Bennett <bennett at sdf.org> ---
     Given that the only user who can pagefix is root, I am not sure how the
new
vm.max_user_wired will be useful.  Further, if it really does what the
description says, it will not solve the problems that vm.max_wired could have
helped with and possible solve if it were properly supported in 11 and 12,
which
appear to be caused by the kernel, not a user program.  And no, there is only
vm.max_wired in 11.  I can't say for 12 at the moment because the laptop that
has 12.1 on it is shut off.  Next time I use it I can look to see whether
vm.max_user_wired is present.
     If a sysctl to limit pagefixing on a per-process basis were added, but not
replacing vm.max_wired, that could be useful in a case of root running
something
that might pagefix too much memory concurrently.  It's a shame that
vm.max_wired
is being dumped instead of repaired.
     In any case, this PR probably ought to be reassigned to the proper team
for
the VM system.
