[ Upstream commit 50b7b6f29de3e18e9d6c09641256a0296361cfee ]
As io_threads are fully set up USER threads it's clearer to separate the
code path from the KTHREAD logic.
The only remaining difference to user space threads is that io_threads
never return to user space again. Instead they loop within the given
worker function.
The fact that they never return to user space means they don't have an
user space thread stack. In order to indicate that to tools like gdb we
reset the stack and instruction pointers to 0.
This allows gdb attach to user space processes using io-uring, which like
means that they have io_threads, without printing worrying message like
this:
warning: Selected architecture i386:x86-64 is not compatible with reported target architecture i386
warning: Architecture rejected target-supplied description
The output will be something like this:

That is not a regression from 5.10.161, right? This release is only for
the io_uring stuff to make sure that backport was done correctly.
The current "to apply" queue for the stable trees is very large right
now due to everyone waiting to get tiny things into -rc1 instead of
before then, so the above two are still not yet queued up, sorry.
thanks,

Sure not a problem, I can resend again later if it is still not queued.
