Yeah, I'm pretty sure I even tested that -EINTR case at one point.
Of course, it could easily have gotten broken again, so that's not a
strong argument.
That said, the "buf->err" handling has always been very confusing, and
it would be lovely to get rid of that confusion.
I don't remember why we did it that way, but I think it's because
low-level filesystems ended up changing the error that the filldir()
function returned or something like that.
