+Subject: [PATCH 3/3] Fix renameat (parallel to previous fix to rename)
+
+There was a bug in rename(), which was duplicated when renameat() was
+implemented, and which got fixed two years ago for rename(), but no
+one ever uses renameat() so it didn't get fixed there. Thanks
+to Anton Gerasimov <anton@advancedtelematic.com> for the bug report
+and patch.
