ZFS Trim

[Beeblebrox]

Hello.
I just recently enabled trim for my SSD + zpool:
/boot/loader.conf => vfs.zfs.trim_disable=0
The SSD hosts root zpool, plus ZIL of second pool hosted on spindle HDD.
Previously I was using the configuration without trim code in loader.conf.

sysctl kstat.zfs.misc.zio_trim shows:
kstat.zfs.misc.zio_trim.unsupported: 106
kstat.zfs.misc.zio_trim.failed: 0

2 questions:
* What does the *trim.unsupported* mean for my setup
* Do I need to run code to fix this (like zpool clean zil) in single-user
mode?

Thank you.
