Subject: mm/damon/sysfs-schemes: use damon_nr_accesses_mvsum() for damo regions
Date: Mon, 29 Jun 2026 21:08:00 -0700

damon_nr_accesses_mvsum() returns a value same to nr_accesses_bp.  Also
the function is more simple and therefore more tolerant to errors. 
Execution of the function would be more expensive than the simple read of
the field, but because the function is quite simple, the overhead should
be negligible.  Use it in the DAMON sysfs interface for scheme-tried
regions, instead of the nr_accesses_bp.
