Subject: [PATCH vfs-2.6:for-next] Push BKL down into ->remount_fs() v2
Date: Tue, 12 May 2009 15:10:53 +0200
Message-Id: <1242133854-4872-1-git-send-email-abogani@texware.it>
X-Mailer: git-send-email 1.6.0.4
Sender: linux-kernel-owner@vger.kernel.org

X-Mailing-List: linux-kernel@vger.kernel.org

Push the BKL acquisition from vfs to every specific filesystems
with hope that it can be eliminated in a second moment.

Changes from previous version:

Removed useless BKL from some filesystems which don't require it.

Reduced BKL acquisition as short as possible.
