I think that space before ':' can go away. Although that's preexisting,
so could also be a separate patch, I guess.

This isn't a proper sentence, so I don't think it should have a
full-stop. And it shouldn't start with an uppercase letter, either.

Hm... "read" is the "direction". Perhaps "indicates the direction of a
transfer"? Or perhaps "indicates that the transfer is a read access"?
