After the recent import from OpenZFS it has become possible to import ZFS pools witn an active org.illumos:edonr feature on FreeBSD, leading to a panic. In addition, "zpool status" reported all pools without edonr as upgradable and "zpool upgrade -v" lists edonr in the list of upgradable features.
To avoid the panic and eventual FS corruption we should deploy a fix even before it has been accepted upstream.
