io-wq: remove io_wq_flush and IO_WQ_WORK_INTERNAL
io_wq_flush() is buggy, during cancelation of a flush, the associated work may be passed to the caller's (i.e. io_uring) @match callback. That callback is expecting it to be embedded in struct io_kiocb. Cancelation of internal work probably doesn't make a lot of sense to begin with. As the flush helper is no longer used, just delete it and the associated work flag. Signed-off-by: Pavel Begunkov <asml.silence@gmail.com> Signed-off-by: Jens Axboe <axboe@kernel.dk>
