Subject: [PATCH 01/50] nfs41: prevent exchange_id from sending server-only flag
Date: Fri, 13 Aug 2010 17:31:13 -0400 [thread overview]
Message-ID: <1281735122-1496-2-git-send-email-andros@netapp.com> (raw)
In-Reply-To: <1281735122-1496-1-git-send-email-andros@netapp.com>
From: Fred Isaman <iisaman@citi.umich.edu>
clp->cl_exchange_flags is used both for client output and server input.
This causes problems in certain recovery situations, when the server
has sent back EXCHGID4_FLAG_CONFIRMED_R, causing the client to erroneously
use the flag in future EXCHANGE_ID requests.
