I was thinking you could use DAMOS stat[1] for the schemes and assuming no reply to it as an agreement, but maybe I should made it clear. Do you think DAMOS stat cannot be used instead? If so, what would be the limitation of DAMOS stat for your usage? > > > 3.

Unless I get a good enough test setup and results from it on my own or from others' help, your test result would be the last requirement for dropping RFC from this patchset. > Sorry, I will have another break this week. No problem, I hope you to have nice break. Nobody can chase/push others. We all do this work voluntarily for our own fun and profit, right? ;) [1] https://lore.kernel.org/damon/20240405060858.2818-1-honggyu....@sk.com Thanks, SJ > > Thanks, > Honggyu
