Timeout update is a IORING_OP_TIMEOUT_REMOVE request with timeout_flags containing a new IORING_TIMEOUT_UPDATE flag. Even though naming may be confusing, but update and remove are very similar both code and functionality wise, so doesn't seem necessary to add a new opcode. Updates don't support offsets, but I don't see a need either. Can be implemented in the future by passing it in sqe->len.
