Merge tag 'io_uring-6.10-20240703' of git://git.kernel.dk/linux

Pull io_uring fix from Jens Axboe:
 "A fix for a feature that went into the 6.10 merge window actually
  ended up causing a regression in building bundles for receives.

  Fix that up by ensuring we don't overwrite msg_inq before we use
  it in the loop"
