Can you clarify what you mean by "that way" here?

Presumably, only NETPOLL_TARGET_DYNAMIC needs CONFIGFS_FS=y ?

Maybe none of this matters: NETPOLL_TARGET itself *can* be a module,
as it doesn't do anything more than stack a target management layer on
top of the existing netpoll code. Nothing in this patchset actually
changes anything within netpoll itself.
