Hi Ryusuke, This is sixth version of the patch set. v5->v6 * Minor corrections in logic of free inodes calculation (remove obsolete increment, align indentations). * Rework patch on using atomic64_t instead of using atomic_long_t (Joern Engel suggestion). v4->v5 * Remove mi_desc_blocks_count field from nilfs_mdt_info struct. * Remove logic of using mi_desc_blocks_count from the code. * Simplify logic of nilfs_palloc_count_max_entries() method. * Add single patch with changing on atomic_long_t type representation of inodes_count and blocks_count fields in nilfs_root struct. v3->v4 * The desc_blocks value is represented by unsigned long type. * The nilfs_palloc_count_desc_blocks() method is simplified. * The mi_desc_blocks_count field of nilfs_mdt_info structure is represented as atomic64_t for the case of CONFIG_64BIT and as atomic_t for other cases. v2->v3 * Trivial BUG_ON checks were removed. * Whole calculation algorithm was moved into nilfs_palloc_count_max_entries() method. * Improve error processing in the code. * The nilfs_palloc_mdt_file_can_grow() method was simplified. * The nilfs_ifile_count_free_inodes() method was simplified. v1->v2 * Change __statfs_word on u64 type. * Rename nilfs_count_free_inodes() into nilfs_ifile_count_free_inodes() method. * Introduce auxiliary functions: nilfs_palloc_count_max_entries(), nilfs_palloc_count_desc_blocks(), nilfs_palloc_mdt_file_can_grow(). * Rework processing of returned error from nilfs_ifile_count_free_inodes() in nilfs_statfs().
