Re: ZFS TRIM support committed to HEAD.

Hi,

Switched to AHCI and now looks more plausible:

kstat.zfs.misc.zio_trim.zio_trim_bytes: 2173466624
kstat.zfs.misc.zio_trim.zio_trim_success: 13244
kstat.zfs.misc.zio_trim.zio_trim_unsupported: 0
kstat.zfs.misc.zio_trim.zio_trim_failed: 0

I'll report back if anything unpleasant happens. Thanks to all for this.
