SeongJae Park a5b2e43378 mm/damon/core: use damos_commit_quota_goal() for new goal commit 
commit 7eca961dd7 upstream.

When damos_commit_quota_goals() is called for adding new DAMOS quota goals
of DAMOS_QUOTA_USER_INPUT metric, current_value fields of the new goals
should be also set as requested.

However, damos_commit_quota_goals() is not updating the field for the
case, since it is setting only metrics and target values using
damos_new_quota_goal(), and metric-optional union fields using
damos_commit_quota_goal_union().  As a result, users could see the first
current_value parameter that committed online with a new quota goal is
ignored.  Users are assumed to commit the current_value for
DAMOS_QUOTA_USER_INPUT quota goals, since it is being used as a feedback.
Hence the real impact would be subtle.  That said, this is obviously not
intended behavior.

Fix the issue by using damos_commit_quota_goal() which sets all quota goal
parameters, instead of damos_commit_quota_goal_union(), which sets only
the union fields.

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 reStructuredText 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.
