From: Josef Bacik Subject: [PATCH 3/6] Ocfs2: handle hole punching via fallocate properly Date: Mon, 15 Nov 2010 12:05:20 -0500 Message-ID: <1289840723-3056-4-git-send-email-josef@redhat.com> References: <1289840723-3056-1-git-send-email-josef@redhat.com> To: david@fromorbit.com, linux-kernel@vger.kernel.org, linux-btrfs@vger.kernel.org, linux-ext4@vger.kernel.org, linux-fsdevel@vger.kernel.org, xfs@oss.sgi.com, cmm@us.ibm.com, cluster-dev Return-path: In-Reply-To: <1289840723-3056-1-git-send-email-josef@redhat.com> Sender: linux-btrfs-owner@vger.kernel.org List-Id: linux-ext4.vger.kernel.org This patch just makes ocfs2 use its UNRESERVP ioctl when we get the hole punch flag in fallocate. I didn't test it, but it seems simple enough.
