It depends on the operation. ext2meta[1] works fine for online defrag, just exporting metadata objects and providing read(1) and write(2) operations on them. Adding 'trigger' files (like your add_this_extent_to_inode) may make sense for some operations, indeed, but we need to see the whole picture before really understanding whether that interface is optimal.
