This is needed for the kernel buffer cache conversion to be able
to wait on IO synchrnously. It is implemented with pthread mutexes
and conditional variables.

I am inclined to not merge patches 4 or 5 until there's something that
uses it. It can be merged and tested together with consumers, rather
than adding unused code at this point.  Thoughts?

I think I will let Dave answer this question since I believe he most likely
has a roadmap on when the consumers will land.

Technically speaking, one /could/ port xfs_scrub to use the kernel
completion API instead of calling pthread APIs directly, but I don't see
much gain from churning that.
