From a08aa355af18c53f17f499c1cc6e2af66a77ba9b Mon Sep 17 00:00:00 2001 From: Ilia Mirkin Date: Tue, 24 May 2011 17:13:30 -0700 Subject: lru_cache: use correct type in sizeof for allocation This has no actual effect, since sizeof(struct hlist_head) == sizeof(struct hlist_head *), but it's still the wrong type to use.
