Against the latest mmotm. (rc7-mm1) Major changes from previous one is - page_cgroup allocation/lookup manner is changed. all FLATMEM/DISCONTIGMEM/SPARSEMEM and MEMORY_HOTPLUG is supported. - force_empty is totally rewritten. and a problem that "force_empty takes long time" in previous version is fixed (I think...) - reordered patches. - first half are easy ones. - second half are big ones. I'm still testing with full debug option. No problem found yet. (I'm afraid of race condition which have not been caught yet.) [1/12] avoid accounting special mappings not on LRU. (fix) [2/12] move charege() call to swapped-in page under lock_page() (clean up) [3/12] make root cgroup to be unlimited. (change semantics.) [4/12] make page->mapping NULL before calling uncharge (clean up) [5/12] make page->flags to use atomic ops. (changes in infrastructure) [6/12] optimize stat. (clean up) [7/12] add support function for moving account. (new function) [8/12] rewrite force_empty to use move_account. (change semantics.) [9/12] allocate all page_cgroup at boot. (changes in infrastructure) [10/12] free page_cgroup from LRU in lazy way (optimize) [11/12] add page_cgroup to LRU in lazy way (optimize) [12/12] fix race at charging swap (fix by new logic.) *Any* comment is welcome. Thanks, -Kame
