Third take of the I/O topology patches. This time against Jens' 2.6.31
tree.
Changes:
- Remove the notion of hardsect_size as it about to become a confusing
anachronism. Use logical_block_size to refer to the block size used
when talking to the device via ATA/SCSI.
- Use the term physical_block_size to refer to the device physical
sector size.
(Logical and physical are the terms used in the T10/T13 standards).
- Move queue limits to an embedded struct so DM can get rid of its
internal I/O restriction housekeeping and use the same stacking
function as MD.
- Switch MD to new stacking API. Once MD has been updated, the old
stacking function can be removed.
