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.

   mm/zswap: add the flag can_sleep_mapped

Haven't been able to actually test these yet, but looks good to me so 
far, so

I have tested that this patch works well，it's better to double check 
by you or someone else.

Is there anyone else testing this patch?

Can I send an official patch out?

Please wait a bit for Mike, Sebastian or me to actually test this.
Also, keep them CC'd explicitly if you are to come up with a new
version for some reason.

Best regards,
