udf_release_file() can be called from munmap() path with mmap_sem held. Thus we cannot take i_mutex there because that ranks above mmap_sem. Luckily, i_mutex is not needed in udf_release_file() anymore since protection by i_data_sem is enough to protect from races with write and truncate. Reported-by:
