| Subject: io_uring: don't check req->file in io_fsync_prep() |
| |
| From: Jens Axboe <axboe@kernel.dk> |
| |
| commit ec858afda857e361182ceafc3d2ba2b164b8e889 upstream. |
| |
| This is a leftover from the really old days where we weren't able to |
| track and error early if we need a file and it wasn't assigned. Kill |
| the check. |
