I already tried it https://lkml.org/lkml/2012/8/8/37 but I didn't get any response from you guys. I think zram/zsmalloc's code qulity is good and they are used for many embedded vendors for a long time. So it's proper time to promote them. The zram should put on under driver/block/. I think it's not arguable but the issue is which directory we should keep *zsmalloc*. Now Nitin want to keep it with zram so it would be in driver/blocks/zram/ But I don't like it because zsmalloc touches several fields of struct page freely(and AFAIRC, Andrew had a same concern with me) so I want to put it under mm/. In addtion, now zcache use it, too so it's rather awkward if we put it under dirver/blocks/zram/. So questions. To Andrew: Is it okay to put it under mm/ ? Or /lib? To Jens: Is it okay to put zram under drvier/block/ If you are okay, I will start sending patchset after I sort out zsmalloc's location issue. -- Kind regards, Minchan Kim
