SeongJae Park 81c5d125ff mm/damon/sysfs: update monitoring target regions for online input commit 
commit 9732336006 upstream.

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.

README 

Linux kernel
============

There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.

In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``.  The formatted documentation can also be read online at:

    https://www.kernel.org/doc/html/latest/

There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.

Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
