Hi Moritz,

The patch is for NFS client side bug where it was initializing the
attributes to zero if NFS4ERR_MOVED is returned in LOOKUP; but referral was
not followed later. This only happens with NFSv4 server and the specific
error (NFS4ERR_MOVED).

It is not related to nfs-ganesha - it can be reproduced with kernel NFS as
well.

Are you seeing any regressions with the patch?

Thanks,
Pradeep
