I disagree: I want to keep the variable declaration blocks small; I'd rather
not even put the inline functions in there that I did.  I only did that because
you wanted the #ifdef count reduced.

The slow_work_rq debugging interface is not strictly necessary, but it proved a
useful debugging tool.  I emailed Linus before I went on holiday and asked if
he was willing to take these not-strictly-necessary patches on which other
patches were built, or whether he'd prefer me to drop those patches and adjust
the rest.

Because it did.  That's when I finished my set of patches and published them
before going on holiday for a week - and that in turn was related to when I
came up with a better test case.  Sometimes coincidences do happen.

Possibly.  That just means we have a debugfs ABI instead of a proc ABI - it
needs maintaining either way.  On the other hand, it can be moved there easily
and the docs changed, and doing so makes a reasonable amount of sense - except
that debugfs isn't normally mounted by at least Fedora for some reason.
