 * The i_data_sem and i_mutex serve for protection of allocation information
 * of a regular files and symlinks. This includes all extents belonging to
 * the file/symlink, a fact whether data are in-inode or in external data
 * blocks, preallocation, goal block information... When extents are read,
 * i_mutex or i_data_sem must be held (for reading is enough in case of
 * i_data_sem). When extents are changed, i_data_sem must be held for writing
 * and also i_mutex must be held.
 * For directories i_mutex is used for all the necessary protection.
