Hi, I was going through the do_try_to_free_pages(), balance_pgdat(), __zone_reclaim() functions and I see that shrink_zone and shrink_slab are called for each zone. But, shrink_slab() doesn't seem to bother about the zone from where it is freeing memory. My questions are: - Will this be a strain on the direct/indirect reclamation algorithm ? The loops involved expects to free something from that particular zone. shrink_slab might take more time than is required to free up pages from that particular zone which might not be optimal. Am I right about this conclusion ? - If the above is correct, then is there any work happening on this front, i.e., to make shrink_slab functionality and the shrinker callbacks more zone-centric ? Are there any patches that I could look at or download from somewhere for this ? - Are there any other considerations to be careful of for making shrink_slab more zone centric ? Can there be other side effects that affects performance if the shrink_slab and shrinker callbacks are made to free pages only from a particular zone ?
