So... I see that using TRIM is a scheduled feature for ZFS. This is good --- ZFS's policy of never overwriting active data make's it's use of TRIM all the more important. But I'm concerned about the other side. If I have an iSCSI disk exported from ZFS, will ZFS receive the "UNMAP" (SCSI's TRIM) and free those blocks?
