Comment 1 Robert Frohl 2022-09-15 08:17:25 UTC 
tracking as affected: 

- SLE15-SP4
Comment 3 David Disseldorp 2022-09-22 22:00:48 UTC 
Thanks for the report.

We're not currently carrying any of the chain:
6bf9c47a39891 ("io_uring: defer file assignment")
d5361233e9ab9 ("io_uring: drop the old style inflight file tracking")
9cae36a094e7e ("io_uring: reinstate the inflight tracking")

As such, I don't think we're affected by this, but would like to spend a bit more time confirming.
The fix should apply and work fine atop our current kernel, so even if unaffected we could still consider taking it, in case we do eventually pick up "defer file assignment", etc.
