Author: jeff Date: Fri Aug 13 03:10:48 2010 New Revision: 211260 URL: http://svn.freebsd.org/changeset/base/211260 Log: - Just check the direct buf pointer against NULL rather than assuming it will be set for 64bit systems. This works in more cases. On BSD we may not allocate a direct map for a large non-contiguous region to avoid the vm address space allocator expense.
