Subject[PATCH 2/9] mm/damon/sysfs-schemes: use nr_accesses_bp as the source of tried_regions/<N>/nr_accesses
Date
DAMON sysfs interface exposes access rate of each region via DAMOS tried
regions directory. For this, the nr_accesses field of the region is
used. DAMOS was actually using nr_accesses in the past, but it uses
nr_accesses_bp now. Use the value that it is really using as the
source.

Note that this doesn't expose nr_accesses_bp as is (in basis point), but
after converting it to the natural number by dividing the value by
10,000. Hence there is no behavioral change from users' perspective.
