I agree with this. The two-letter abbreviations are good if they come
from the official documentation. This makes it easy to reference.

For the Linux made up ones, a more descriptive name is better. Then
there wont be confusion when people look at "IR" and can't find it
online or in the document, and scratch their head thinking they are not
smart enough to do kernel development and we lose another kernel
developer ;-)
