| |
2.6.27-stable review patch. If anyone has any objections, please let us know.
------------------ From: Bob Moore <robert.moore@intel.com>
commit 9db4fcd99f7ef886ded97cd26a8642c70fbe34df upstream.
The "minimal" descriptors such as EndTag are calculated as 12 bytes long, but the actual length in the internal descriptor is 16 because of the round-up to 8 on 64-bit build.
