Hi David,

I tried this patch on top of bpf-next but behaviour seems unchanged,
dmesg is at [1].

BTW, I'm hitting the same issue over Linus's tree now, but unfortunately
there is no WA in my case as I don't have "cache=mmap" in rootflags.

It came to Linus with Christian Brauner's pull request.

Thanks,
