commit5a2d162e22upstream. DAMON region end address is exclusive one, but charge_addr_from is assigned assuming the end address is inclusive. As a result, DAMOS action to next up to min_region_sz memory can be skipped. This is quite negligible user impact. But, the bug is a bug that can be very simply fixed. Fix the wrong assignment to respect the exclusiveness of the address. The issue was discovered [1] by Sashiko.

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.
