From 4a718d7dbab873bc24034fc865d3a5442632d1fd Mon Sep 17 00:00:00 2001 From: Christoph Hellwig Date: Wed, 21 Feb 2024 13:58:42 +0100 Subject: xen-blkfront: set max_discard/secure erase limits to UINT_MAX MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Currently xen-blkfront set the max discard limit to the capacity of the device, which is suboptimal when the capacity changes. Just set it to UINT_MAX, which has the same effect and is simpler.
