A refactoring example on moving to treewide, consistent use of a new api may help.

Consider

2efc459d06f1630001e3984854848a5647086232

sysfs: Add sysfs_emit and sysfs_emit_at to format sysfs output

A new api for printing in the sysfs.  How do we use it treewide ?

Done manually, it would be a heroic effort requiring high level maintainers pushing and likely only get partially done.

If a refactoring programatic fixit is done and validated on a one subsystem, it can run on all the subsystems.

The effort is a couple of weeks to write and validate the fixer, hours to run over the tree.

It won't be perfect but will be better than doing it manually.
