Hi Kamezawa-san, As you wrote before (http://lkml.org/lkml/2009/7/22/65) > To be honest, what I expected in these days for people of blockio > cgroup is like following for getting room for themselves. <<snip>> > --- mmotm-2.6.31-Jul16.orig/include/linux/page_cgroup.h > +++ mmotm-2.6.31-Jul16/include/linux/page_cgroup.h > @@ -13,7 +13,7 @@ > struct page_cgroup { > unsigned long flags; > struct mem_cgroup *mem_cgroup; > - struct page *page; > + /* block io tracking will use extra unsigned long bytes */ > struct list_head lru; /* per cgroup LRU list */ > }; Have you already added a room for blkio_cgroup in struct page_cgroup? If not, I would like you to apply the above change to mmotm. The latest blkio-cgroup has reflected the comments you pointed out. I would also like you to give me any comments on it and consider merging blkio-cgroup to mmotm. Thank you for your help in advance.
