[PATCHSET,0/3] xfs: vectorize scrub kernel calls

Message

Hi all,

Create a vectorized version of the metadata scrub and repair ioctl, and
adapt xfs_scrub to use that.  This is an experiment to measure overhead
and to try refactoring xfs_scrub.

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.
