From f061d35150003b7fd5b133d14d66a74500fdaa60 Mon Sep 17 00:00:00 2001 From: Darren Hart Date: Thu, 12 Mar 2009 15:11:18 -0700 Subject: [PATCH] futex: remove the pointer math from double_unlock_hb Impact: simplify code I mistakenly included the pointer value ordering in the double_unlock_hb() in my previous patch. It's only necessary in the double_lock_hb() function. This patch removes it.
