It will for the Intel IMSM raid devices. The external superblock format
support added to mdadm 3.0 allows it to write BIOS recognized metadata
for the IMSM format, so creating an array using mdadm on an IMSM
container will cause mdadm to create arrays that the BIOS recognizes as
valid (and much less tested, any standard DDF format as well, but we
aren't planning on using that, we are leaving DDF format to dmraid which
has much greater test coverage of that format).
