The sum at the beginning of line "intr" includes also unnumbered interrupts.
It implies that the sum at the beginning isn't the sum of the remainder of the
line, not even an estimation.
Fixed the documentation to mention that.

I'm not really doubting what you claim, Jan, but it would be really
helpful if you provided some data to support the proposed change
(Kernel source references, or notes about testing you've done, or
pointers to mailing list threads, authoritative note that you are
the maintainer of some relevant kernel subsystem...). Do you have
something like that? (It's also useful for the change log.)
Thanks,
Michael

I wouldn't mind more of a changelog, but the additional text is
certainly correct.
Thanks. I'll apply the patch, but more changelog comments are welcome.

Sorry -- I wrote the reply in a hurry, having first mistaken the patch
as being something to apply in man-pages. I should have looked more
closely ;-).

Amen.

And I see now that this text could also reasonably fit into the
proc(5) man page. So I've added, with a Reviewed-by: tag for Randy.
Thanks for the text, Jan.

Thank you for applying.
You may add following line to the changelog:
This behaviour was added to /proc/stat in commit a2eddfa95919a730e0e5ed17e9c303fe5ba249cd.

Thanks, Jan -- that's indeed helpful for the man-pages changelog!
