The patch's triviality depends on how one checks for if a file descriptor
refers to a raw device or not. I'm not sure how to do that reliably.

For our purposes it is enough to check if the file-descriptor refers to a
regular file and avoid doing a SEEK_END in that case, but that is probably
not sufficient in the general case.
