Sorry, but I couldn't understand your design. Probably I am missing the bigger picture. I think that for ZFS case it would be sufficient to be able to iterate over detected device names or devspecs. Size and other disk properties do not seem to be needed. Unless I am mistaken, of course. E.g. something akin to what bd_print (dv_print, in the general case) does but oriented towards programmatic use rather than end-user. Maybe all that partition table parsing should be done only once (e.g. in the init method) and the result should be saved. -- Andriy Gapon _______________________________________________ freebsd-hackers@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-hackers To unsubscribe, send any mail to "freebsd-hackers-unsubscr...@freebsd.org"
