Hi SeongJae,
Some questions for this patch:
Why do we split the regions in 3 areas (heap, stack, mmaped)? I
understand we don't want to model the whole virtual address space, but
why don't we just use whatever is modeled by the VMAs to define the
regions boundaries?
I am not quite understanding why we both set the page idle and young (in
damon_ptep_mkold). For WSS computation on our end we have used
pte_clear_young_notify. Why do we touch the page idle flag at all? What
flags do the reclaim logic use to track access?
Kind regards,
Fernand
