SeongJae Park 6813131578 mm/damon/sysfs-schemes: implement quota effective_bytes file 
DAMON sysfs interface allows users to set two types of quotas, namely time
quota and size quota.  DAMOS converts time quota to a size quota and use
smaller one among the resulting two size quotas.  The resulting effective
size quota can be helpful for debugging and analysis, but not exposed to
the user.  The recently added feedback-driven quota auto-tuning is making
it even more mysterious.

Implement a DAMON sysfs interface read-only empty file, namely
'effective_bytes', under the quota goal DAMON sysfs directory.  It will be
extended to expose the effective quota to the end user.
