In genl_bind(), currently genl_lock and write cb_lock are taken
for iteration of genl_fam_idr and processing of static values

as it is sufficient to guard the idr and the struct against
concurrent genl_register/unregister_family() calls.
This will allow to run genl command processing in genl_rcv() and
mnl_socket_setsockopt(.., NETLINK_ADD_MEMBERSHIP, ..) in parallel.
Not stable material, please drop.
Will do, thanks!
