Subject: mm/damon/sysfs: split out kdamond-independent schemes stats update logic into a new function
Date: Mon, 24 Oct 2022 20:49:17 +0000
'damon_sysfs_schemes_update_stats()' is coupled with both
damon_sysfs_kdamond and damon_sysfs_schemes. It's a wide range of types
dependency. It makes splitting the logics a little bit distracting.
Split the function so that each function is coupled with smaller range of
types.
