Subject: [PATCH] Detail: fix segfault during IMSM raid creation
Date: Sun, 22 Nov 2020 23:12:29 +0800	[thread overview]
Message-ID: <20201122151229.16365-1-lidong.zhong@suse.com> (raw)

It can be reproduced with non IMSM hardware and IMSM_NO_PLATFORM
environmental variable set. The array state is inactive when creating
an IMSM container. And the structure info is NULL because load_super()
always fails since no intel HBA information could be obtained.

Signed-off-by: Lidong Zhong <lidong.zhong@suse.com>
Reported-by: Tkaczyk Mariusz <mariusz.tkaczyk@intel.com>
Fixes: 64bf4dff3430 (Detail: show correct raid level when the array is inactive)
