SubjectRE: [PATCH] NFSv4: nfs4_do_fsinfo() should not do implicit lease renewals

>btw: Recent ONTAP versions return NFS4ERR_STALE_CLIENTID which is handled
correctly - Linux client will try to renew its lease and if successful it
will retry open().

One more comment here, although the issue won't manifest to applications
with NetApp fileservers in this case, it is still wrong for the client to
end up in such a state.
Also, you will need to wait longer (keep unmounting/mounting) with NetApp
filers as they seem to have implemented courtesy locks/delayed lease
expiration as per the RFC.
This means to reproduce the issue against NetApp you need to wait at least
2x grace period + 1 minute).

Best regards,
Robert Milkowski
