Changes from v1 (https://lore.kernel.org/damon/20221024204919.18524-1-sj@xxxxxxxxxx/): - 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.
