The structure used for communication between kernel and userspace are
located in include/linux/dm-log-cluster.h.  Due to the frequency,
diversity, and 2-way communication nature of the exchanges between
kernel and userspace, 'connector' is used as the interface for
communication.

Maye I misremember it, but isn't the connector code strongly deprecated
in favour of genetlink?

Use of connector is deprecated, it does not have any advantages over
genetlink while genetlink provides an optional attributes based
protocol interface which allows for messaging protocols to be developed
which can be extended without breaking binary compatibility. It also
features a userspace library which makes development trivial.


I guess nobody will force you but use of genetlink is encouraged.
