For example - how to allow full support for leases (including upgrades/downgrades) and delegations - whether to allow directory leases/delegations - faster file copy; the proper common API into copy offload (allow faster server side copy via either T10-like or CopyChunk mechanisms) - Whether there is value in implementing the new cache/no-cache flags on read/write, and per-write writethrough flag - RichACLs (already mentioned as topic for discussion in earlier posts) Similarly testing of NFSv4.x and SMB3 have many common pain points - and the recent improvements to xfstests allow more testing of network file systems, but also show problems common to both NFS an SMB3. -- Thanks, Steve
