Could you try again with 2.4 on FSAL_VFS?

Unfortunately I don't have a Windows client to test, and Windows is the only
NFS v3 client I know of that uses NLM_SHARE. I would love to understand it's
usage pattern because the NLM spec is not clear on how NLM_SHARE should
behave if the owner already has a share. There is no documentation of share
upgrade/downgrade semantics.

Thanks

Frank
