Bug Description
There's a regression with io_uring reported against 5.11-5.14 kernels, see:
https:/
From reading the thread and looking at the history in linux-stable/
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.
