Tested with your patches on top of linux-next as of yesterday, however starting at commit fa812e869a6fe7495a17150bb2639075081ef709 ("mm/zswap.c: delete an error message for a failed memory allocation in zswap_dstmem_prepare()"), since the "mm: per-lruvec slab stats" patch series breaks everything ;) Tested-by: Heiko Carstens <heiko.carst...@de.ibm.com>
