There are many btrfs functions that manually search the tree for an item. They all reimplement the same mechanism and differ in the conditions that they use to find the item. It has been proposed that a new core interface, btrfs_find_item, be created to take the place of these functions, and standardize the search functionality. This patchset takes the first steps toward the implementation of this core interface. The first patch creates a starting point for the interface by moving one of the search functions, __inode_item, to ctree.c and renaming it with the core function name. The next two patches eliminate one similar helper function each by replacing their callers with calls to the new core function, and modifying the new core function to ensure it fulfills the purpose of the function being replaced.
