[ Upstream commit 77ce220c0549dcc3db8226c61c60e83fc59dfafc ]

The test fails because of a recent fix to the verifier, even though this

That fix is commit b02709587ea3 ("bpf: Fix propagation of 32-bit signed
bounds from 64-bit bounds.") upstream, which only needed backport to 5.9.
So although backporting this patch to 5.4 shouldn't break anything, I
wouldn't bother.

I'll drop it from 5.4, thanks!
