[PATCHSET,v1.0,00/10] fstests: reflink on the realtime device

Hi all,

This patchset enables use of the file data block sharing feature (i.e.
reflink) on the realtime device.  It follows the same basic sequence as
the realtime rmap series -- first a few cleanups; then widening of the
API parameters; and introduction of the new btree format and inode fork
format.  Next comes enabling CoW and remapping for the rt device; new
scrub, repair, and health reporting code; and at the end we implement
some code to lengthen write requests so that rt extents are always CoWed
fully.

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.
