This adds a new selfest to make sure what was fixed (and backported to
stable) remains fixed.
Sure. But we should provide -stable maintainers guidance for "how far
back to go". There isn't much point in backporting this into kernels
where it's known to fail!
I'm probably missing something important.
1) It's a test that does not fall into the common stable kernels
categories (see Documentation/process/stable-kernel-rules.rst).
2) If it fails in a kernel *it achieved its goal* of highlighting that
something serious is broken.
I'm still thinking that we want this in kernels which have 38b43539d64b?
To hide that the other kernels are seriously broken and miss that fix?
Really (1) this shouldn't be backported. I'm not even sure it should be
a selftest (sounds more like a reproducer that we usually attach to
commits, but that's too late). And if people care about backporting it,
(2) you really want this test to succeed everywhere. Especially also to
find kernels *without* 38b43539d64b
