+Subject: [PATCH] open_without_symlink: Account when prefix is empty string
+
+In the current implementation, the open_without_symlink function
+will default to opening the root mount only if the passed rootfs
+prefix is null. It doesn't account for the case where this prefix
+is passed as an empty string.
+
+Properly handle this second case as well.
+
+Upstream-Status: Accepted
