(specifically, I want a file on an ext3 fs to act as one of the raid-members

because both mkfs and mount (with -o loop) will accept a file as a
block-device, but I have found no such function for mdadm, and am thus asking
for a kernel-internal way to re-plug a file into the block-device layer.
Is this possible?
Sure! You just have to create the loop device (/dev/loop*) yourself using
losetup(8). `mount -o loop' does it itself behind your back.
