+Subject: [PATCH] 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.
