From 738be136327a56e5a67e1942a2c318fb91914a3f Mon Sep 17 00:00:00 2001 From: Christoph Hellwig Date: Wed, 21 Feb 2024 13:58:43 +0100 Subject: xen-blkfront: rely on the default discard granularity MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit The block layer now sets the discard granularity to the physical block size default. Take advantage of that in xen-blkfront and only set the discard granularity if explicitly specified.
