24  * This file implements the functions that access LEB properties and their
34  * get_heap_comp_val - get the LEB properties value for heap comparisons.
35  * @lprops: LEB properties
54  * @lprops: LEB properties to move
91  * @lprops: LEB properties to move
170  * add_to_lpt_heap - add LEB properties to a LEB category heap.
172  * @lprops: LEB properties to add
221  * remove_from_lpt_heap - remove LEB properties from a LEB category heap.
223  * @lprops: LEB properties to remove
247  * @old_lprops: LEB properties to replace
248  * @new_lprops: LEB properties with which to replace
268  * ubifs_add_to_cat - add LEB properties to a category list or heap.
270  * @lprops: LEB properties to add
273  * LEB properties are categorized to enable fast find operations.
308  * ubifs_remove_from_cat - remove LEB properties from a category list or heap.
310  * @lprops: LEB properties to remove
313  * LEB properties are categorized to enable fast find operations.
342  * @old_lprops: LEB properties to replace
343  * @new_lprops: LEB properties with which to replace
373  * ubifs_ensure_cat - ensure LEB properties are categorized.
375  * @lprops: LEB properties
395  * ubifs_categorize_lprops - categorize LEB properties.
397  * @lprops: LEB properties to categorize
399  * LEB properties are categorized to enable fast find operations. This function
400  * returns the LEB category to which the LEB properties belong. Note however
402  * LEB properties may have their category changed to %LPROPS_UNCAT.
437  * change_category - change LEB properties category.
439  * @lprops: LEB properties to re-categorize
441  * LEB properties are categorized to enable fast find operations. When the LEB
442  * properties change they must be re-categorized.
494  * is_lprops_dirty - determine if LEB properties are dirty.
496  * @lprops: LEB properties to test
512  * ubifs_change_lp - change LEB properties.
514  * @lp: LEB properties to change
520  * This function changes LEB properties (@free, @dirty or @flag). However, the
522  * the updated LEB properties on success and a negative error code on failure.
524  * Note, the LEB properties may have had to be copied (due to COW) and
643  * ubifs_change_one_lp - change LEB properties.
645  * @lnum: LEB to change properties for
652  * This function changes properties of LEB @lnum. It is a helper wrapper over
679 		ubifs_err("cannot change properties of LEB %d, error %d",  in ubifs_change_one_lp()
685  * ubifs_update_one_lp - update LEB properties.
687  * @lnum: LEB to change properties for
718 		ubifs_err("cannot update properties of LEB %d, error %d",  in ubifs_update_one_lp()
724  * ubifs_read_one_lp - read LEB properties.
726  * @lnum: LEB to read properties for
727  * @lp: where to store read properties
729  * This helper function reads properties of a LEB @lnum and stores them in @lp.
743 		ubifs_err("cannot read properties of LEB %d, error %d",  in ubifs_read_one_lp()
759  * This function returns LEB properties for a LEB with free space or %NULL if
783  * This function returns LEB properties for an empty LEB or %NULL if the
806  * This function returns LEB properties for a freeable LEB or %NULL if the
830  * This function returns LEB properties for a freeable index LEB or %NULL if the
1012  * @lp: LEB properties to scan
1013  * @in_tree: whether the LEB properties are in main memory
1017  * (%LPT_SCAN_CONTINUE), whether the LEB properties should be added to the tree
1250  * dbg_check_lprops - check all LEB properties.
1253  * This function checks all LEB properties and makes sure they are all correct.
