[PATCH v2 0/4] skip swapcache for super fast device

With fast swap storage, platform want to use swap more aggressively and swap-in is crucial to application latency. The rw_page based synchronous devices like zram, pmem and btt are such fast storage. When I profile swapin performance with zram lz4 decompress test, S/W overhead is more than 70%. Ma
