Subject: [RFC mm/zswap 0/2] Fix the compatibility of zsmalloc and zswap
Date: Fri, 25 Dec 2020 19:02:49 +0800	[thread overview]
Message-ID: <1608894171-54174-1-git-send-email-tiantao6@hisilicon.com> (raw)

patch #1 add a flag to zpool, then zswap used to determine if zpool
drivers such as zbud/z3fold/zsmalloc whether can sleep in atoimc context.
patch #2 set flag sleep_mapped to true indicates that zbud/z3fold can
sleep in atomic context. zsmalloc didin't support sleep in atomic context,
so not set that flag to true.

Tian Tao (2):
  mm/zswap: add the flag can_sleep_mapped
  mm: set the sleep_mapped to true for zbud and z3fold
