From a2a9f16838509475ea6801f7794a89e03d55e3ed Mon Sep 17 00:00:00 2001 From: Yu Kuai Date: Fri, 25 Aug 2023 11:09:55 +0800 Subject: [PATCH] md: don't check 'mddev->pers' from suspend_hi_store() Now that mddev_suspend() doean't rely on 'mddev->pers' to be set, it's safe to remove such checking. This will also allow the array to be suspended even before the array is ran.
