6.12-stable review patch. If anyone has any objections, please let me know.

From: SeongJae Park sj@kernel.org
commit 7d390b53067ef745e2d9bee5a9683df4c96b80a0 upstream.
damon_commit_schemes() ignores quota goals and filters of the newly committed schemes. This makes users confused about the behaviors. Correctly handle those inputs.
