The '.tx_done_cleanup' is also added in this patch, can you please separate it 
to another patch?

'descriptor_done' dev_ops is removed from this patch in this version, but the 
clutter seems remained, like above function and relevant function declerations 
etc.., can you please clean them all?


dropping this patch form the patchset, because of the issues above. Can you 
please send new version as an icremental patch?
