Great!  Thanks for this.

Any chance you can document the following sysctls?

root@kaos:/root # sysctl -d kstat.zfs.misc.zio_trim
kstat.zfs.misc.zio_trim:=20
kstat.zfs.misc.zio_trim.zio_trim_bytes:=20
kstat.zfs.misc.zio_trim.zio_trim_success:=20
kstat.zfs.misc.zio_trim.zio_trim_unsupported:=20
kstat.zfs.misc.zio_trim.zio_trim_failed:=20

Glen
