[for-6.13 PATCH v3 00/14] nfs/nfsd: improvements for LOCALIO

[Mike Snitzer <snitzer@kernel.org>]

Hi,

All available here:
https://git.kernel.org/pub/scm/linux/kernel/git/snitzer/linux.git/log/?h=nfs-localio-for-next

Changes since v2:
- switched from rcu_assign_pointer to RCU_INIT_POINTER when setting to
  NULL.
- removed some unnecessary #if IS_ENABLED(CONFIG_NFS_LOCALIO)
- revised the NFS v3 probe patch to use a new nfsv3.ko modparam
  'nfs3_localio_probe_throttle' to control if NFSv3 will probe for
  LOCALIO. Avoids use of NFS_CS_LOCAL_IO and will probe every
  'nfs3_localio_probe_throttle' IO requests (defaults to 0, disabled).
- added "Module Parameters" section to localio.rst

All review appreciated, thanks.
Mike
