Message

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

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.

Damien Le Moal (4):
  block: bfq: fix bfq_set_next_ioprio_data()
  block: fix ioprio interface
  block: rename IOPRIO_BE_NR
  block: fix default IO priority handling
