Subject: [RFC PATCH 01/17] netlabel: Mark rcu pointers with __rcu.
Date: Tue, 22 Dec 2015 11:46:37 +0000	[thread overview]
Message-ID: <1450784813-18304-2-git-send-email-huw@codeweavers.com> (raw)

This fixes sparse errors of the form:
 netlabel_domainhash.c:126:23: error: incompatible types in comparison expression (different address spaces)

This patch also removes unnecessary initialization of static variables
to NULL.
