This series fixes problems with IO priority values handling and cleans
up several macro names and code for clarity.

Changes from v2:
* Fixed typo in a comment in patch 3
* Added reviewed-by tags

Changes from v1:
* Added patch 4 to unify the default priority value used in various
  places.
* Fixed patch 2 as suggested by Bart: remove extra parenthesis and move
  ioprio_valid() from the uapi header to the kernel header.
* In patch 2, add priority value masking.
