This function: - instantiates `cls(config)` on the meta device - scans `named_modules()` for candidate modules - optionally pre-filters them with `target_modules_patterns` - uses `is_fusable(...)` as the final structural check - builds the class-level patch mapping used by monkey patching Results are cached per `(fusion_name, cls)` to avoid repeated meta-initialization. This matches the current class-level fusion behavior, where one compatible module class maps to one fused replacement class. metaN|)r setdefaultrRr9setrrecompilejoin named_modulesrsearchr$addr(r) rjr)rkrlcachemodel seen_classes patch_mappingtarget_module_pattern module_namer module_clss r_discover_fusable_modulesrs"( $ . .{B ?E e|Sz f F 5LM>B>Z>Z 388D889:`d %224 O V&\  %  ,1F1M1Mk1Z1b v& $-1-B-B:-N j))* OE#J +s DDc zt||||}|s/tj|j|jyt |dt |drt |jdstd|jd|jj}|j|}t|}|l|Dcic]}t|j|} }|D]?} t| j} | j| } | ,td |d |d | d ||z}t||dycc}w) aRegister one fusion family for `cls`.
