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.
