+Subject: SUNRPC: Fix loop termination condition in gss_free_in_token_pages()
+
+From: Chuck Lever <chuck.lever@oracle.com>
+
+commit 4a77c3dead97339478c7422eb07bf4bf63577008 upstream.
+

+the following KASAN splat:
+
+  KASAN: maybe wild-memory-access in range [0x04a2013400000008-0x04a201340000000f]
