[PATCH v13 00/19] nfs/nfsd: add support for localio

[Mike Snitzer <snitzer@kernel.org>]

These latest changes are available in my git tree here:
https://git.kernel.org/pub/scm/linux/kernel/git/snitzer/linux.git/log/?h=nfs-localio-for-next

Changes since v12:
- Rebased to rearrange code to avoid "churn" that Jeff Layton felt
  distracting (biggest improvement came from folding switch from
  struct file to nfsd_file changes in from the start of the series)
- Updated relevant patch headers accordingly.
- Updated localio.rst to provide more performance data.
- Dropped v12's buggy "nfsd: fix nfsfh tracepoints to properly handle
  NULL rqstp" patch -- fixing localio to support fh_verify tracepoints
  will need more think-time and discussion, but they aren't of
  critical importance so fixing them doesn't need to hold things up.

Please also see v12's patch header for v12's extensive changes:

Thanks,
Mike
