As best I can tell, there are exactly two comments in that file (I don't count the licensing and ahem CVS metadata), and neither of them add any enlightenment at all. Kernel development must be a very special culture. I tried finding the equivalent file in the Linux kernel, but while looking I saw there is at least one example of commentary to go along with a struct: https://sourcegraph.com/github.com/torvalds/linux/-/blob/dri...
