[v10,00/19] nfs/nfsd: add support for localio

Message

Mike Snitzer June 30, 2024, 4:37 p.m. UTC

Hi,

Changes since v9:
- Inverted series so that NFSD changes come before NFS.
- Addressed many of Chuck's various review comments for "[PATCH v9
  13/19] nfsd: add "localio" support"

TODO:
- Hopefully get a favorable response to this patch from XFS engineers:
  https://marc.info/?l=linux-xfs&m=171976530416523&w=2
  (otherwise, will need to revisit using dedicated workqueue patch)

All review and comments are welcome!

Thanks,
Mike
