So I spent a while thinking hard about how I could make Tobin do another
round or two on these patches. But then I figure that it's the holidays,
and I should just apply them. So that's done. Thanks for all of your
work on this!

That said...

- I don't quite understand why you capitalize "kernel" everywhere. I
vaguely recall some sort of discussion on that. To me it looks
strange...oh well.

- There's a dangling reference to printk-formats.txt in lib/vsprintf.c
that we'll want to fix up.

- The vsprintf kerneldoc currently gets pulled into the big "kernel API"
dumpster. Someday, it would be nice to turn printk-formats.rst into a
"how to output data from the kernel" section, with documentation on
vnsprintf, printk, trace_printk, and format strings all in one place.
What a fine day that would be...

Thanks again,
