So, I've got this very-cephfs-specific piece of pgls filtering code in ReplicatedPG: https://github.com/ceph/ceph/commit/907a3c5a2ba8e3edda18d7edf89ccae7b9d91dc5 I'm not sure I'm sufficiently motivated to create some whole new plugin framework for these, but what about piggy-backing on object classes? I guess it would be an additional cls_register_filter("myfilter", my_callback_constructor) fn. tl;dr; How do people feel about extending object classes to include providing PGLS filters as well?
