Subject[PATCH] block: add queue_logical_block_mask() and bdev_logical_block_mask()
Date
Introduce queue_logical_block_mask() and bdev_logical_block_mask()
to simplify code, which replace (queue_logical_block_size(q) - 1)
and (bdev_logical_block_size(bdev) - 1).

Like wo done for fs.
This round we add helpers and start converting in the next cycle.
