Hi: I was reading mm/memory.c the page faults management part. Does every major fault corresponding to a disk read? And a minor fault to only an allocation of page frame? by the comment in do_swap_page: ............ /* Had to read the page from swap area: Major fault */ 1145 ret = 2; ............. but the line: 1131 page = read_swap_cache_async(entry); may result in a cache hit, right? Thanks. jean __________________________________________________ Do You Yahoo!? Yahoo!
