It's backported to all LTS kernels for multiple years and this
nonsensical theory of using a software version with O_DIRECTORY |
O_CREAT on a pre-LTS kernel from years ago is just flimsy.

Even just the mere fact that I was able to just backport that bugfix
that started returning hard errors to all LTS kernels with absolutely
zero regression reports defeats that argument. We've done way more
invasive changes. This is a strawman really.
