io_uring: fix fs cleanup on cqe overflow If completion queue overflow occurs, __io_cqring_fill_event() will update req->cflags, which is in a union with req->work and happens to be aliased to req->work.fs. Following io_free_req() -> io_req_work_drop_env() may get a bunch of different problems (miscount fs->users, segfault, etc) on cleaning @fs.
