This series fixes problems with IO priority values handling and cleans up several macro names and code for clarity. Changes from v3: * Split former patch 2 into patches 2, 3 and 4 to facilitate review and have more descriptive commit titles. * In patch 5, keep IOPRIO_BE_NR as an alias for the new IOPRIO_NR_LEVELS macro. Change this patch title and commit message accordingly. * In patch 6, define IOPRIO_BE_NORM as an alias of IOPRIO_NORM. 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.
