Instead, it only helps +other kernel components such as subsystems and modules building their data +access-aware applications using DAMON's core features. For this, DAMON exposes +its all features to other kernel components via its application programming +interface, namely ``include/linux/damon.h``. Please refer to the API +:doc:`document ` for details of the interface.
