Re: [syzbot] [io-uring?] INFO: task hung in io_wq_put_and_exit (6)

[Jens Axboe]

Just to wrap this one up - there's a fairly lengthy explanation posted
here:

https://lore.kernel.org/io-uring/937c3e38-368e-43eb-9d7e-2dcc0697799f@xxxxxxxxx/

which details why this isn't really a bug, it's just slow exit due to
the odd huge reads (and number of them) syzbot queues up with io_uring
before exiting.
