Changes from v1
(https://lore.kernel.org/damon/20221024204919.18524-1-sj@kernel.org/):
- Add 10th patch, which splits schemes sysfs directory implementation

This patchset cleans up and refactors a range of DAMON code including
the core, DAMON sysfs interface, and DAMON modules, for better
readability and convenient future feature implementations.

In detail, this patchset splits unnecessarily long and complex functions
in core into smaller functions (patches 1-4).  Then, it cleans up the
DAMON sysfs interface by using more type-safe code (patch 5) and
removing unnecessary function parameters (patch 6).  Further, it
refactor the code by distributing the code into multiple files (patches
7-10).  Last two patches (patches 11 and 12) deduplicates and remove
unnecessary header inclusion in DAMON modules (reclaim and lru_sort).

Note that this initially posted as a part of a feature implementation
RFC patchset[1], but separated into this patchset as the amount of the
change is not small compared to the feature implementation change
itself.
