[CRIU] [criu]launch page-server in swrk mode

[Dengguangxing]

Hi all,

I am trying to lauch a page-server through criu swrk mode.

The page-server will always exit with one pre-dump/dump call(with page-server opts).
I've tried to set keep_open flag as true in rpc request. and it just acts the same way.

Am I wrong with the page-server swrk mode? How to lauch a page-server daemon in swrk mode
and make it survive serveral pre-dumps?

Thanks!
Best Regards
Deng
