Quite a number of sysctl variable names have changed, and the port needs to be adapted to the new names (therefore there are lots of 0 values in the -L output). The following names used by zfs-stats do not exist in OpenZFS: kstat.zfs.misc.arcstats.recycle_miss kstat.zfs.misc.arcstats.l2_write_buffer_bytes_scanned kstat.zfs.misc.arcstats.l2_write_buffer_iter kstat.zfs.misc.arcstats.l2_write_buffer_list_iter kstat.zfs.misc.arcstats.l2_write_buffer_list_null_iter kstat.zfs.misc.arcstats.l2_write_full kstat.zfs.misc.arcstats.l2_write_in_l2 kstat.zfs.misc.arcstats.l2_write_io_in_progress kstat.zfs.misc.arcstats.l2_write_not_cacheable kstat.zfs.misc.arcstats.l2_write_passed_headroom kstat.zfs.misc.arcstats.l2_write_pios kstat.zfs.misc.arcstats.l2_write_spa_mismatch kstat.zfs.misc.arcstats.l2_write_trylock_fail kstat.zfs.misc.arcstats.l2_writes_hdr_miss vfs.zfs.vdev.cache.size The existence of vfs.zfs.vdev.cache.size vs vfs.zfs.vdev.cache_size can be used to detect OpenZFS, and is easily fixed. But the above listed L2ARC values seem to have been removed from or have never existed in OpenZFS, and I did not find any substitutes. Are there any plans to re-create them in OpenZFS on FreeBSD or are they gone for good?

I'd like to update the zfs-stats port for compatibilíty with OpenZFS ...
