From ee0b31a25a010116f44fca6c96f4516d417793dd Mon Sep 17 00:00:00 2001 From: Mimi Zohar Date: Tue, 17 Jan 2012 20:39:51 +0000 Subject: keys: fix trusted/encrypted keys sparse rcu_assign_pointer messages Define rcu_assign_keypointer(), which uses the key payload.rcudata instead of payload.data, to resolve the CONFIG_SPARSE_RCU_POINTER message: "incompatible types in comparison expression (different address spaces)" Replace the rcu_assign_pointer() calls in encrypted/trusted keys with rcu_assign_keypointer().
