From d5391bf02b9dc6a84fe33ba913caf70061909950 Mon Sep 17 00:00:00 2001 From: Heinrich Schuchardt Date: Wed, 31 Aug 2022 16:37:35 +0200 Subject: efi_loader: ensure all block devices are probed Only probed block devices are available in the UEFI sub-system. Multiple block devices may be involved in the boot process. So we have to make sure that all block devices are probed. Another reason is that we store UEFI variables on the ESP which may be on any block device.
