3.18-stable review patch. If anyone has any objections, please let me know.
------------------
From: Dan Carpenter <dan.carpenter@xxxxxxxxxx>
commit db86be3a12d0b6e5c5b51c2ab2a48f06329cb590 upstream.
We're freeing the list iterator so we should be using the _safe()
version of hlist_for_each_entry().
Fixes: 88b4a07e6610 ("[PATCH] eCryptfs: Public key transport mechanism")
