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.
