SeongJae Park 9732336006 mm/damon/sysfs: update monitoring target regions for online input commit
When user input is committed online, DAMON sysfs interface is ignoring the
user input for the monitoring target regions.  Such request is valid and
useful for fixed monitoring target regions-based monitoring ops like
'paddr' or 'fvaddr'.

Update the region boundaries as user specified, too.  Note that the
monitoring results of the regions that overlap between the latest
monitoring target regions and the new target regions are preserved.

Treat empty monitoring target regions user request as a request to just
make no change to the monitoring target regions.  Otherwise, users should
set the monitoring target regions same to current one for every online
input commit, and it could be challenging for dynamic monitoring target
regions update DAMON ops like 'vaddr'.  If the user really need to remove
all monitoring target regions, they can simply remove the target and then
create the target again with empty target regions.
