+Subject: [PATCH] Invalidate LVM caches in blivet device discovery loop
+ (#1824418)
+
+This should work around a problem where we sometimes fail to
+correctly evaluate existing logical volumes, though it is not a
+correct fix for the underlying problem (which we haven't exactly
+identified yet) but a workaround for Fedora 32 release.
