For large blocksizes the number of block bits is larger than PAGE_SHIFT,
so calculate the sector number from the byte offset instead. This is
required to enable large folios with buffer-heads.

This is not relevant to older kernels as we had no buffer-head usage of
large folios before v6.15. So this is just creating noise / drama for
older kernels.
Sure, I'll drop it.
Where's that code for auto-sel again?
