Message-Id: <1397242665-2183-2-git-send-email-lczerner@redhat.com> Date: Fri, 11 Apr 2014 20:57:43 +0200 From: Lukas Czerner <lczerner@...hat.com> To: linux-fsdevel@...r.kernel.org Cc: linux-ext4@...r.kernel.org, xfs@....sgi.com, ceph-devel@...r.kernel.org, Lukas Czerner <lczerner@...hat.com> Subject: [PATCH 2/4] fs: Prevent doing FALLOC_FL_ZERO_RANGE on append only file Currently punch hole and collapse range fallocate operation are not allowed on append only file. This should be case for zero range as well. Fix it.
