From 46f19270265fe54cda1c728cb156b755273b4ab6 Mon Sep 17 00:00:00 2001 From: Mariusz Tkaczyk Date: Thu, 23 May 2024 12:06:36 +0200 Subject: [PATCH 100/157] imsm: fix first volume autolayout with IMSM_NO_PLATFORM Autolayout_imsm() is not executed if IMSM_NO_PLATFORM=1 is set. This causes that first volume cannot be created. Disk for new volume are never configured. Fix it by making autolayout_imsm() independent from super->orom because NULL there means that IMSM_NO_PLATFORM=1 is set. There are not platform restrictions to create volume, we just analyze drives. It is safe.
