One patch per change please and also describe each individual change.

Please follow the "one change per patch" rule. This is a widely followed rule in the Linux kernel community. This rule exists because it is the responsibility of the developer(s) who post a patch series to make it easy for reviewers to review their work. Thanks, Bart.
