+Subject: [PATCH] smem: fix support for --source option (python3)
+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+Using --source doesn't work without this patch:
+Traceback (most recent call last):
+  File "./smem", line 727, in <module>
+    showpids()
+  File "./smem", line 299, in showpids
+    showtable(pt.keys(), fields, columns.split(), options.sort or 'pss')

+  File "./smem", line 118, in totalmem
+    _totalmem = memory()['memtotal']
+  File "./smem", line 193, in memory
+    m = f.match(l)
+TypeError: cannot use a string pattern on a bytes-like object
+
+python3's tarfile returns bytes, whereas all of the rest of
+the code assumes str.
+
+Fix the tarfile usage to convert to str before returning the
+results.

+Signed-off-by: André Draszik <git@andred.net>
+Upstream-Status: Inappropriate [upstream wants to support python2 & python3]
