It looks like there are no reasons to have this restriction which makes it harder for a user to quickly check if the endpoint list has been correctly populated by an automated tool. Best to go back to the previous behaviour then. mptcp_pm_gen.c has been modified using ynl-gen-c.py: $ ./tools/net/ynl/ynl-gen-c.py --mode kernel \ --spec Documentation/netlink/specs/mptcp_pm.yaml --source \ -o net/mptcp/mptcp_pm_gen.c The header file doesn't need to be regenerated.
