From mboxrd@z Thu Jan 1 00:00:00 1970 Return-Path: Received: from mail-pa0-f53.google.com ([209.85.220.53]:35819 "EHLO mail-pa0-f53.google.com" rhost-flags-OK-OK-OK-OK) by vger.kernel.org with ESMTP id S1751046AbbKFSk2 (ORCPT ); Fri, 6 Nov 2015 13:40:28 -0500 From: Justin Maggard To: fstests@vger.kernel.org, linux-btrfs@vger.kernel.org Cc: Justin Maggard Subject: [PATCH] btrfs: test quota disable during quota rescan Date: Fri, 6 Nov 2015 10:40:21 -0800 Message-Id: <1446835221-11905-1-git-send-email-jmaggard@netgear.com> Sender: linux-btrfs-owner@vger.kernel.org List-ID: This test case tests if we are able to disable quotas on a filesystem while a quota rescan is running. Up to now (4.3) this would result in a kernel NULL pointer dereference. Fixed by patch (btrfs: qgroup: fix quota disable during rescan).
