Here is rc5 of the new port.
* Fix import
* Add memory pressure
Since lack-of-memory-pressure-sensing was the last missing piece, this version is "feature complete".
We are now testing towards release.
(Performance would have been poor in versions before this due to deflated ARC)
macos-2.0.0-rc5-0-g2596ec6ac9
(We changed tags from zfs to macos, as it turns out ZOL has zfs-2.0.0-rc5)
Remember that BigSur does not let go of the old kext easily. Check the version
with "zpool version" and if old will not go, use the trigger-panic-medic method.
