#     Merge tag 'io_uring-5.9-2020-08-15' of git://git.kernel.dk/linux-block
#     
#     Pull io_uring fixes from Jens Axboe:
#      "A few differerent things in here.
#     
#       Seems like syzbot got some more io_uring bits wired up, and we got a
#       handful of reports and the associated fixes are in here.
#     
#       General fixes too, and a lot of them marked for stable.
#     
#       Lastly, a bit of fallout from the async buffered reads, where we now
#       more easily trigger short reads. Some applications don't really like
#       that, so the io_read() code now handles short reads internally, and
#       got a cleanup along the way so that it's now easier to read (and
#       documented). We're now passing tests that failed before"
