+Subject: [PATCH] Fix reading hidden sysfs attribute
+
+util.get_sysfs_attr returns a string so bool(hidden) is always
+True and we hide all devices.

+Subject: [PATCH] Ignore devices marked as hidden in sysfs(#1856974)
+

+are visible in /sys/block but not directly usable so we should
+ignore these as well as all devices with the hidden attribute.
