123 * Each DAMON-based operation scheme (&struct damos) has its own apply
124 * interval, and we need to expose the scheme tried regions based on only
126 * scheme. The status becomes 'idle' at the beginning.
137 * the scheme is completely applied to the given snapshot. Hence the callback
147 * apply intervals of the scheme is passed while the state is 'idle'.
