Author: ed Date: Sun Jun 9 08:28:23 2013 New Revision: 251566 URL: http://svnweb.freebsd.org/changeset/base/251566 Log: Fix the way atomic_is_lock_free() is defined for Clang. When using Clang atomics, atomic types are not placed in a structure. There is thus no reason why we should get the __val member.
