[PATCH v2 0/2] lockd: allow setting ports without setting gracetime

[Jeff Layton <jlayton@kernel.org>]

This version fixes some selftest coverage gaps that Sashiko pointed out.
The actual bugfix is unchanged.

This patchset fixes a rather silly bug that Scott pointed out to me in a
meeting recently. You currently can't set the ports in lockd via the
netlink interface unless you also set the gracetime. This patch makes
them all properly optional.

Changes in v2:
- selftests: split put_ports() into put_tcp_port()/put_udp_port() helpers
- selftests: attributes_are_set_independently now also covers a UDP-only SERVER_SET
- selftests: empty_set_is_a_noop and settings_are_per_netns now set and check gracetime too
- Link to v1: https://lore.kernel.org/r/20260923-nfsd-testing-v1-0-a793f54a4dd1@kernel.org
