loop-AES version 1 on-disk format as implemented by the kernel driver, is
compatible with cryptoloop AES up to 2 TB device size. However, the userpace
key setup part of mount and losetup programs most likely are not compatible
by default (didn't look at gentoo patch).
loop-AES version 2 and 3 on-disk formats are not compatible with mainline.
Securitywise, loop-AES-v1 / cryptoloop on-disk format is busted. Don't ever
consider using those.

Last time I checked, loop-AES was faster, but I haven't speed tested
mainline crypto code for long time.
