Does version 5.1 here mean running tests from Linux 5.1, against older kernels?

MSG_ZEROCOPY for UDP was added in commit b5947e5d1e71 ("udp:
msg_zerocopy") in Linux 5.0.

The selftest was expanded with this feature in commit db63e489c7aa
("selftests: extend zerocopy tests to udp"), also in Linux 5.0.

Those tests are not expected to pass on older kernels.
