[PATCHSET,v1.0,00/10] libxfs: refactor rt extent unit conversions

Message

Hi all,

This series replaces all the open-coded integer division and
multiplication conversions between rt blocks and rt extents with calls
to static inline helpers.  Having cleaned all that up, the helpers are
augmented to skip the expensive operations in favor of bit shifts and
masking if the rt extent size is a power of two.

If you're going to start using this mess, you probably ought to just
pull from my git trees, which are linked below.

This is an extraordinary way to destroy everything.  Enjoy!
Comments and questions are, as always, welcome.
