#     
#     POull io_uring fix from Jens Axboe:
#      "Just fixing a silly braino in a previous patch, where we'd end up
#       failing to compile if CONFIG_BLOCK isn't enabled.
#     
#       Not that a lot of people do that, but kernel bot spotted it and it's
#       probably prudent to just flush this out now before -rc6.
#     
#       Sorry about that, none of my test compile configs have !CONFIG_BLOCK"
