Subject: [PATCH v4 0/6] IO priority fixes and improvements
Date: Wed, 11 Aug 2021 12:36:56 +0900 [thread overview]
Message-ID: <20210811033702.368488-1-damien.lemoal@wdc.com> (raw)
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.
