[PATCH v3 0/2] mm/damon: Fix fake /proc/loadavg reports

[SeongJae Park]

This patchset fixes DAMON's fake load report issue.  The first patch
makes yet another variant of usleep_range() for this fix, and the second
patch fixes the issue of DAMON by making it using the newly introduced
function.

I think these need to be applied on v5.15.y, but the second patch cannot
cleanly applied there as is.  I will back-port this on v5.15.y and post
later once this is merged in the mainline.  If you think this is not
appropriate for stable tree, please let me know.
