Why do you promote zsmalloc in this patchset? > It might make you hard to merge even zswap into staging. When I look at [8/9], I realized you are trying to merge this patch into mm/, NOT staging. I don't know history why zsmalloc/zram/zscache was in staging at the beginning but personally, I don't ojbect zswap into /mm directly because I got realized staging is very deep hole to get out, expecially related to mm stuff. ;-) -- Kind regards, Minchan Kim -- To unsubscribe, send a message with 'unsubscribe linux-mm' in the body to majordomo@xxxxxxxxx.
