From 0629e370dd5819efa5cf8d418a8e6729efe388ef Mon Sep 17 00:00:00 2001 From: Alexandros Batsakis Date: Sat, 5 Dec 2009 13:46:14 -0500 Subject: nfs41: check SEQUENCE status flag the server can indicate a number of error conditions by setting the appropriate bits in the SEQUENCE operation. The client re-establishes state with the server when it receives one of those, with the action depending on the specific case.
