Bug description:
There's a regression with io_uring reported against 5.11-5.14 kernels,
see:
https://lore.kernel.org/io-uring/CABVffEOXe=mhyW_-
ynz4z9g_uxvvams662vqjn9ubff9nhw...@mail.gmail.com/T/#m8bf4fdb4c91d8ea231517d9f936d1e4354c40a3b
From reading the thread and looking at the history in
linux-stable/linux-5.15.y,
I assume that Linux 5.15.3 is the first fully fixed version.
And 5.10 was not affected.
Sadly all other versions are EOL for kernel.org.
But ubuntu provides 5.11, 5.13 and 5.14 based kernels,
which most likely have the bug.
I'm reporting it against linux-hwe-5.13 as that's what I test on most systems,
but others e.g. linux-oem-5.13 and linux-oem-5.14 have the same problem.
