io_uring: fix !CONFIG_BLOCK compilation failure
kernel test robot correctly pinpoints a compilation failure if CONFIG_BLOCK isn't set: fs/io_uring.c: In function '__io_complete_rw': >> fs/io_uring.c:2509:48: error: implicit declaration of function 'io_rw_should_reissue'; did you mean 'io_rw_reissue'? [-Werror=implicit-function-declaration] 2509 | if ((res == -EAGAIN || res == -EOPNOTSUPP) && io_rw_should_reissue(req)) { | ^~~~~~~~~~~~~~~~~~~~ | io_rw_reissue cc1: some warnings being treated as errors Ensure that we have a stub declaration of io_rw_should_reissue() for !CONFIG_BLOCK. Fixes: 230d50d448ac ("io_uring: move reissue into regular IO path") Reported-by: kernel test robot <lkp@intel.com> Signed-off-by: Jens Axboe <axboe@kernel.dk>
