Hi, sorry for bothering but is there some opinions on this series?
(I've found that epoll change log has not been well refreshed and
says that this fdinfo feature is config-checkpoint-restore dependant,
but in real this config entry was ripped off during conversation).
So, at moment I somehow confused since it's a bit unclear where to
move, either this series is more-less acceptible or not. I could
bring back all config-checkpoint-restore dependency (since I still
believe this feature better to be enabled not by default but iif
user has asked fo it).
