I found a patch for this at http://lwn.net/Articles/324023/, but it has some journal block estimation problem resulting into deadlock. I would like to know if it has been solved. If not, is it possible to solve it? What are the complexities involved? Please help. Thanks in advanced. Regards, Kailas
