[RFC 2/8] mm/damon/sysfs-schemes: expose nr_accesses_bp via tried_regions/<N>/nr_accesses

[SeongJae Park <sj@kernel.org>]

DAMON sysfs interface exposes access rate of each region via DAMOS tried
regions directory.  For this, the nr_accesses field of the region is
being used.  DAMOS was using nr_accesses in the past, but it uses
nr_accesses_bp now.  Expose the value that it is really using.  Note
that it 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.
That's for not making unnecessary confusion to the old users.
