Message-ID: <56A02144.9030206@redhat.com> Date: Wed, 20 Jan 2016 18:07:32 -0600 MIME-Version: 1.0 List-Id: XFS Filesystem from SGI List-Unsubscribe: , List-Archive: List-Post: List-Help: List-Subscribe: , Content-Type: text/plain; charset="us-ascii" Content-Transfer-Encoding: 7bit Errors-To: xfs-bounces@oss.sgi.com Sender: xfs-bounces@oss.sgi.com To: xfs@oss.sgi.com, dwysocha@redhat.com The current explanation is a bit vague to the uninitiated; clarify the text to make it obvious that while the mkfs.xfs utility is able to create valid filesystems with block sizes up to 65536, the Linux kernel can only mount filesystems with page sized or smaller blocks.
