+Subject: [PATCH 3/3] Fix TypeError: unorderable types: str() > int() in
+ arc_summary.py
+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+Running arc_summary.py with a l2arc cache device around produces
+the following error:
+
+  Traceback (most recent call last):
+    File "/usr/bin/arc_summary.py", line 1148, in <module>
+      main()
+    File "/usr/bin/arc_summary.py", line 1144, in main
+      page(Kstat)
+    File "/usr/bin/arc_summary.py", line 724, in _l2arc_summary
+      arc["l2_arc_evicts"]["reading"] > 0:
+  TypeError: unorderable types: str() > int()
+
+This is due to arc["l2_arc_evicts"]['lock_retries'] and
+arc["l2_arc_evicts"]["reading"] both being strings, returned
+from fHits() earlier. Rather than adding them up and checking
+if the result is > 0, this checks if either string is != '0'.
