Still too much in a single patch.

Changing printk's to pr_info and pr_cont is patch noise as far as I'm
concerned.  Adds no value, and just breaks other patches.  Ditto using
__func__ and and coalesing formats (much of which was broekn up back
when checkpatch flamed developers about 80 column lines, and I patch
noises from trivial patch monkeys offering to fix it, sigh).

And I really don't care about adding EXT4-fs to debugging messages,
especially messages which can't be enabled except when developers have
to explicitly add #define's...

One evidence that this patch is noise is that it doesn't apply cleanly
just on top of my current patch set that I plan to send to Linus.  And
I consider it a waste of time to sort through and figure out what if
any of this 1200 line patch is really worthwhile.  (A quick scan
didn't find anything, although if there are some places where I'm
missing a pr_cont / KERN_CONT in a commonly used --- non debug ---
codepath I'd be willing to fix it.)
