121  * considered "young". This is used by shrinker when selecting znode to trim
257  * Return codes used by the garbage collector.
259  * @LEB_FREED_IDX: indexing LEB was freed and can be used only after the commit
342  * This data structure is used to temporary store garbage-collected indexing
364  * @bulk_read: non-zero if bulk-read should be used
371  *                 currently stored on the flash; used only for regular file
373  * @ui_size: inode size used by UBIFS when writing to flash
375  * @compr_type: default compression type used for this inode
398  * The @synced_i_size field is used to make sure we never write pages which are
441  * is used to clean the LEB when remounting to read-write mode.
456  * LPROPS_HEAP_CNT: number of heaps used for storing categorized LEBs
519  * @total_used: total used space in bytes (does not include index LEBs)
526  * used by itself (in which case 'unused_lebs' would be a better name). In the
656 /* Callback used by the 'ubifs_lpt_scan_nolock()' function */
668  * @used:  number of used bytes in the write-buffer
674  * @lock: serializes @buf, @lnum, @offs, @avail, @used, @next_ino and @inodes
686  * Note: the fields @buf, @lnum, @offs, @avail and @used can be read under
689  * spin-lock. Thus the data between @buf and @buf + @used can be read under
698 	int used;
845  * @comp_mutex: mutex used during compression
846  * @decomp_mutex: mutex used during decompression
880  * @idx_growth, @data_growth and @dd_growth are not used in budget request. The
927  * if this orphan is a xattr, not used otherwise.
979  * @nospace: non-zero if the file-system does not have flash space (used as
1022  * @highest_inum: highest used inode number
1037  * @cmt_bud_bytes: used during commit to temporarily amount of bytes in
1041  * @bud_bytes: how many bytes of flash is used by buds
1075  * @gap_lebs: array of LEBs used by the in-gaps commit method
1085  * @bottom_up_buf: a buffer which is used by 'dirty_cow_bottom_up()' in tnc.c
1102  * @lpt_lebs: number of LEBs used for lprops table
1105  * @orph_lebs: number of LEBs used for the orphan area
1129  *                used to store indexing nodes (@leb_size - @max_idx_node_sz)
1136  * @dirty_pg_cnt: number of dirty pages (not used)
1143  * @calc_idx_sz: temporary variable which is used to calculate new index size
1155  *                data nodes of maximum size - used in free space reporting
1185  * @gc_lnum: LEB number used for garbage collection
1186  * @sbuf: a buffer of LEB size used by GC and replay for scanning
1222  * @lpt_buf: buffer of LEB size used by LPT
1251  * @hash_tfm: the hash transformation used for hashing nodes
1253  * @hmac_desc_len: length of the HMAC used for authentication
1255  * @auth_hash_name: the name of the hash algorithm used for authentication
1256  * @auth_hash_algo: the authentication hash used for this fs
1266  * @replay_list: temporary list used during journal replay
