The thing is that I know what queue_logical_block_size - 1 does.
That's the low bits.  _Which_ bits are queue_logical_block_mask?
The high bits or the low bits?  And before you say "It's obviously",
we have both ways round in the kernel today.

I am not in favour of this change.  I might be in favour of bool
queue_logical_block_aligned(q, x), but even then it doesn't seem worth
the bits.
