If an operation's flag `needs_file` is set, the function io_req_set_file() calls io_file_get() to obtain a `struct file*`.
This fails for `O_PATH` file descriptors, because those have no `struct file*`
O_PATH descriptors most certainly *do* have that. What the hell are you talking about?
Yeah, hence I was interested in the test case. Since this is bypassing that part, was assuming we'd have some logic error that attempted a file grab for a case where we shouldn't.
