+From: Gui Hecheng <guihc.fnst@cn.fujitsu.com>
+
+The bug accurs when exec:
+        # mkfs.btrfs -r <a relative path> <device>
+        (note: the path should be 'valid' correspond to your `pwd`)
+error msg:
+        $ scandir for <a relative path> failed: No such file...
+
+Replace strdup() with realpath() to get the correct scan path.
+
+Upstream-Status: Backport (pending)
