Resend to remove noise!
Given the current constraints of the current implementation, struct_ops
cannot be registered dynamically. This presents a significant limitation
for modules like fuse-bpf, which seeks to implement a new struct_ops
type. To address this issue, here it proposes the introduction of a new
API. This API will enable the registering of new struct_ops types from
modules.
The following code is an example of how to implement a new struct_ops type
in a module with the proposed API. It adds a new type bpf_testmod_ops in
the bpf_testmod module. And, call register_bpf_struct_ops() and
unregister_bpf_struct_ops() when init and exit the module.
register_bpf_struct_ops() api implementation is missing in the diff.
Sorry for the confusion!
The purpose of this RFC to check how people think about the API itself.
