From: Trond Myklebust Date: Sun, 5 Jul 2015 19:26:58 +0000 (-0400) Subject: NFSv4.1: Handle SEQ4_STATUS_BACKCHANNEL_FAULT correctly X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=b13529059cf782f9b4e4ac0ca9d524bd922163da;p=linux.git NFSv4.1: Handle SEQ4_STATUS_BACKCHANNEL_FAULT correctly RFC5661 states: The server has encountered an unrecoverable fault with the backchannel (e.g., it has lost track of the sequence ID for a slot in the backchannel). The client MUST stop sending more requests on the session's fore channel, wait for all outstanding requests to complete on the fore and back channel, and then destroy the session. Ensure we do so...
