Why is this document part of Linux code base ?
How will the other OSes be aware of this ?
I assume there was some repository to maintain such DSDs so that it
is accessible for other OSes. I am not agreeing or disagreeing on the
change itself, but I am concerned about this present in the kernel
code.
