Hi again Daniel.

Perhaps the format is better written as "%pIScp"
with the port after the compression as that's how
the actual output would be produced.

etc...

Please coalesce formats. It doesn't matter if
the coalesced format exceeds 80 cols.

		pr_debug("%s: sending window update SACK - asoc:%p rwnd:%u a_rwnd:%u\n",
			 __func__, asoc, asoc->rwnd, asoc->a_rwnd);

btw:  what I try to do with formats and args
is to use a single line when it fits 80 cols
and otherwise put all arguments after the
format on a separate line.

etc...
