Having a former release-engineer & disk-I/O renovator on the UFS2
team took care of that: We tried to be future compatible, and UFS2
will look four different places for the superblock: +64k, +8k, +0k
and +256k, (the latter named SBLOCK_PIGGY because somebody senior
thought even 64k was an outrageous waste of space :-)
