None of these should be valid anymore. 1 is ancient, and all the more
recent testing and reports I see of this are not even related to
io_uring, or the original report.

2 should be fixed Linus's tree, and 3 was fixed for 6.11 as it isn't
really important. But my two attempts at getting a re-run of those had a
failure on the syzbot side.

Please close them, thanks.
