Description shineway 2023-03-02 15:40:23 UTC 
Description of problem:

A client should be able to handle getting an EACCES error while doing
a mount operation to reclaim state due to NFS4CLNT_RECLAIM_REBOOT
being set. If the server returns RPC_AUTH_BADCRED because authentication
failed when we execute "exportfs -au", then RECLAIM_COMPLETE will go a
wrong way. After mount succeeds, all OPEN call will fail due to an
NFS4ERR_GRACE error being returned.

I see. I've commented on PR and suggested we'd better post another bugzilla for ANCK-4.19.
