From mboxrd@z Thu Jan 1 00:00:00 1970 Return-Path: linux-nfs-owner@vger.kernel.org Received: from mailhub.sw.ru ([195.214.232.25]:40154 "EHLO relay.sw.ru" rhost-flags-OK-OK-OK-OK) by vger.kernel.org with ESMTP id S1755166Ab2KZMTw (ORCPT ); Mon, 26 Nov 2012 07:19:52 -0500 Subject: [PATCH 2/5] nfsd: make delegations shutdown network namespace aware To: bfields@fieldses.org From: Stanislav Kinsbursky Cc: linux-nfs@vger.kernel.org, Trond.Myklebust@netapp.com, linux-kernel@vger.kernel.org, devel@openvz.org Date: Mon, 26 Nov 2012 15:22:03 +0300 Message-ID: <20121126122203.955.90909.stgit@localhost.localdomain> In-Reply-To: <20121126121907.955.25349.stgit@localhost.localdomain> References: <20121126121907.955.25349.stgit@localhost.localdomain> MIME-Version: 1.0 Content-Type: text/plain; charset="utf-8" Sender: linux-nfs-owner@vger.kernel.org List-ID: NFSv4 delegations are stored in global list. But they are nfs4_client dependent, which is network namespace aware already. State shutdown and laundromat are done per network namespace as well. So, delegations unhash have to be done in network namespace context.
