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?
