Yes, but this should be layered on top of the page handling --- there's no need to integrate it into the low levels of the page cache. > 9) We need also to implement write clustering for fs/page cache/swap. Same as above. When the pagebuf layer or whatever gets a write request for a given page, it is perfectly at liberty to write out adjacent pages too if it wants to. The VM doesn't have to enforce that itself. Cheers, Stephen -- To unsubscribe, send a message with 'unsubscribe linux-mm' in the body to majordomo@kvack.org.
