This patch set adds support in block & elevator layers for handling
urgent requests.
Urgent request notification passed to underlying driver (eMMC for
example) and causes interruption of low priority current request in
order to execute the urgent one.
The interrupted request is inserted back to the scheduler's internal
data structures.
