I am working to add defragment function of zsmalloc. Hi Minchan -- I would be very interested in your design thoughts on how you plan to add defragmentation for zsmalloc. In particular, I am wondering if your design will also handle the requirements for zcache (especially for cleancache pages) and perhaps also for ramster. In https://lkml.org/lkml/2013/3/27/501 I suggested it would be good to work together on a common design, but you didn't reply. Are you thinking that zsmalloc improvements should focus only on zram, in which case we may -- and possibly should -- end up with a different allocator for frontswap-based/cleancache-based compression in zcache (and possibly zswap)? I'm just trying to determine if I should proceed separately with my design (with Bob Liu, who expressed interest) or if it would be beneficial to work together.
