Hello Sage,

I recall that lookups-by-inode could historically return -ESTALE if the
inode in question was no-longer in the MDS cache.  This presumably
removes that deficiency?

Is there any other functionality that needs to be added to Ceph (or
related tooling) to make NFS re-export of a CephFS mount robust?

Cheers,
David
