Subject: mm/damon/sysfs: split out kdamond-independent schemes stats update logic into a new function
Date: Wed, 26 Oct 2022 22:59:40 +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.
