X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=87e2831c3fa39cbf6f7ab676bb5aef039b9659e2;p=GitHub%2Fexynos8895%2Fandroid_kernel_samsung_universal8895.git AIO: fix cleanup in io_submit_one(...) When IOCB_FLAG_RESFD flag is set and iocb->aio_resfd is incorrect, statement 'goto out_put_req' is executed. At label 'out_put_req', aio_put_req(..) is called, which requires 'req->ki_filp' set.
