Hi,

Since an epoll fd can be added to another epoll fd, I'm wondering if you
have enough data here to figure that out. The inode is the
'anon_inode_inode', so I'm wondering if that is sufficient to distinguish it
from other anonymous inodes, or if an extra bit is required to indicate if
the target file is in fact and epoll fd.

I think it should be ebough (together with sdev and pos). But will
look more closely tomorrow once I sit implementing criu support :)
(that's why it is early rfc, to gather comments)
