+Subject: [PATCH] metadata: allow reading metadata with invalid creation_time
+
+lvm2 till version 2.02.169 (commit 78d004efa8a1809cea68283e6204edfa9d7c1091)
+was printing invalid creation_time argument into metadata on 32bit arch.
+
+However with commit ba9820b14223b731125c83dbc9709aa44fdcdbf1 we started
+to properly validate all input numbers and thus we refused to accept
+invalid metadata with 'garbage' string - but this results in the
+situation where metadata produced on older lvm2 on 32 bit architecture
+will become unreadable after upgrade.
+
+To fix this case - extend libdm parser in a way, that whenever we
+find error integer value, we also check if the parsed value is not for
+creation_time node and in this case we let the metadata pass through
+with made-up date 2018-05-24 (release date of 2.02.169).
