No Indian author in 2011 Booker long-list!

Out of a total of 138 books, only 13 have been included in the 2011 Booker long list. No Indian author this year. India has an impressive list of Booker-winning authors ( Salman Rushdie and Arundhati Roy among them), And Booker Prize is regarded highly in India. It is really frustrating to see that none of the authors figures in the list. Not even Amitav Ghosh whose River of Smoke is getting rave reviews in newspapers and magazines. Does not the Booker judges consider it worth it? or is the novel short of literary merit?
