into the FreeBSD test suite There's no functional change with these testcases; they're purposely being left in TAP format for the time being Other testcases which crash on amd64/i386 as-is have not been integrated yet (they need to be retested on a later version of CURRENT, as I haven't used i386 in some time) MFC after: 3 weeks Sponsored by: EMC / Isilon Storage Division
