![]() During BKL removal in 2.6.38, conversion of files from in-ICB format to normal format got broken. We call ->writepage with i_data_sem held but udf_get_block() also acquires i_data_sem thus creating A-A deadlock. We fix the problem by dropping i_data_sem before calling ->writepage() which is safe since i_mutex still protects us against any changes in the file. Also fix pagelock - i_data_sem lock inversion in udf_expand_file_adinicb() by dropping i_data_sem before calling find_or_create_page().
