17ccae8bb5c928 mm/damon/vaddr-test.h SeongJae Park 2021-09-07 44 * discontiguous regions which cover every mapped areas. However, the three
17ccae8bb5c928 mm/damon/vaddr-test.h SeongJae Park 2021-09-07 45 * regions should not include the two biggest unmapped areas in the original
17ccae8bb5c928 mm/damon/vaddr-test.h SeongJae Park 2021-09-07 46 * mapping, because the two biggest areas are normally the areas between 1)
17ccae8bb5c928 mm/damon/vaddr-test.h SeongJae Park 2021-09-07 47 * heap and the mmap()-ed regions, and 2) the mmap()-ed regions and stack.
17ccae8bb5c928 mm/damon/vaddr-test.h SeongJae Park 2021-09-07 48 * Because these two unmapped areas are very huge but obviously never accessed,
17ccae8bb5c928 mm/damon/vaddr-test.h SeongJae Park 2021-09-07 49 * covering the region is just a waste.

17ccae8bb5c928 mm/damon/vaddr-test.h SeongJae Park 2021-09-07 51 * '__damon_va_three_regions() receives an address space of a process. It
17ccae8bb5c928 mm/damon/vaddr-test.h SeongJae Park 2021-09-07 52 * first identifies the start of mappings, end of mappings, and the two biggest
17ccae8bb5c928 mm/damon/vaddr-test.h SeongJae Park 2021-09-07 53 * unmapped areas. After that, based on the information, it constructs the
17ccae8bb5c928 mm/damon/vaddr-test.h SeongJae Park 2021-09-07 54 * three regions and returns. For more detail, refer to the comment of
17ccae8bb5c928 mm/damon/vaddr-test.h SeongJae Park 2021-09-07 55 * 'damon_init_regions_of()' function definition in 'mm/damon.c' file.
17ccae8bb5c928 mm/damon/vaddr-test.h SeongJae Park 2021-09-07 56 *
17ccae8bb5c928 mm/damon/vaddr-test.h SeongJae Park 2021-09-07 57 * For example, suppose virtual address ranges of 10-20, 20-25, 200-210,
17ccae8bb5c928 mm/damon/vaddr-test.h SeongJae Park 2021-09-07 58 * 210-220, 300-305, and 307-330 (Other comments represent this mappings in
17ccae8bb5c928 mm/damon/vaddr-test.h SeongJae Park 2021-09-07 59 * more short form: 10-20-25, 200-210-220, 300-305, 307-330) of a process are
17ccae8bb5c928 mm/damon/vaddr-test.h SeongJae Park 2021-09-07 60 * mapped. To cover every mappings, the three regions should start with 10,
17ccae8bb5c928 mm/damon/vaddr-test.h SeongJae Park 2021-09-07 61 * and end with 305. The process also has three unmapped areas, 25-200,
17ccae8bb5c928 mm/damon/vaddr-test.h SeongJae Park 2021-09-07 62 * 220-300, and 305-307. Among those, 25-200 and 220-300 are the biggest two
17ccae8bb5c928 mm/damon/vaddr-test.h SeongJae Park 2021-09-07 63 * unmapped areas, and thus it should be converted to three regions of 10-25,
17ccae8bb5c928 mm/damon/vaddr-test.h SeongJae Park 2021-09-07 64 * 200-220, and 300-330.
