I believe that the code that you are looking at refers to a old command that is only implemented by CompactFlash cards. The ad(4) driver does not currently support the TRIM command. I have an internal patch that implements it for FreeBSD 8.2; if there's interest I could try to dig it out. _______________________________________________ freebsd-current@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-current To unsubscribe, send any mail to "freebsd-current-unsubscr...@freebsd.org"
