+Subject: Convert trailing spaces and periods in path components
+
+From: Boris Protopopov <pboris@amazon.com>
+
+commit 57c176074057531b249cf522d90c22313fa74b0b upstream.
+
+When converting trailing spaces and periods in paths, do so
+for every component of the path, not just the last component.
+If the conversion is not done for every path component, then
+subsequent operations in directories with trailing spaces or
+periods (e.g. create(), mkdir()) will fail with ENOENT. This
+is because on the server, the directory will have a special
+symbol in its name, and the client needs to provide the same.
