Description Vivek Goyal 2010-05-25 21:44:04 UTC
Description of problem:

Add a padding field to request_list structure. I am expecting there will
be more development in IO controller in RHEL6 life cycle and this structure
should get modified for per group request descriptors and that will break

So adding padding can help backporting new functionality at the same time
preserve kabi.
