Thanks for the report. This is an entertaining typo:

diff --git a/fs/namei.c b/fs/namei.c
index 7bb0419a083d..3d3674c21d3c 100644
--- a/fs/namei.c
+++ b/fs/namei.c
@@ -193,7 +193,7 @@ getname_flags(const char __user *filename, int flags)
                }
                /* The empty path is special. */
                if (unlikely(!len) && !(flags & LOOKUP_EMPTY)) {
-                       __putname(result);
+                       __putname(kname);
                        kfree(result);
                        return ERR_PTR(-ENOENT);
                }

Folding this into the patch.
