+Subject: [PATCH 2/2] Ignore unbootable kernels in /lib/modules
+
+The previous commit didn't ignore zfcpdump kernels if found in
+/lib/modules because we didn't apply the kernel filter to those paths.
+
+Also this commit cleans up the code in general, splitting up the
+multi-purpose "kernel_filter" function into two parts with clearer
+roles.
+
+Fixes: commit 9fbe476d4df0b01568d3668e6121cae7c779c8c7
+Fixes: https://bugzilla.redhat.com/show_bug.cgi?id=2027375
