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.
