--- Comment #7 from Konstantin Belousov <kib@FreeBSD.org> ---
(In reply to Keith White from comment #5)
object->resident_page_fault is equally meaningless for your purposes.  What=
 is
not clear in my comment #4 ?

The patch does not require any of these dynamic calculations using meaningl=
ess
(for this purpose) values.  If you want to limit the tmpfs mount memory use,
specify explicit limit to mount_tmpfs.  The attempts to mis-use some pageda=
emon
or object internal counters would not work out, their purpose is very diffe=
rent
and they do not match with resource limiting for tmpfs.
