If anyone has any objections, please let me know. ------------------ From: Abdun Nihaal [ Upstream commit eb2cb7dab60f9be0b435ac4a674255429a36d72c ] In the error paths after fb_info structure is successfully allocated, the memory allocated in fb_deferred_io_init() for info->pagerefs is not freed. Fix that by adding the cleanup function on the error path.
