Message-Id: <1289248327-16308-4-git-send-email-josef@redhat.com> Date: Mon, 8 Nov 2010 15:32:05 -0500 From: Josef Bacik <josef@...hat.com> To: linux-kernel@...r.kernel.org, linux-btrfs@...r.kernel.org, linux-ext4@...r.kernel.org, linux-fsdevel@...r.kernel.org, xfs@....sgi.com, joel.becker@...cle.com, cmm@...ibm.com, cluster-devel@...hat.com Subject: [PATCH 4/6] Ext4: fail if we try to use hole punch Ext4 doesn't have the ability to punch holes yet, so make sure we return EOPNOTSUPP if we try to use hole punching through fallocate. This support can be added later.
