	Pass an additional pointer of bpf_struct_ops_link to callback function reg, unreg, and update provided by subsystems defined in bpf_struct_ops. A bpf_struct_ops_map can be registered for multiple links. Passing a pointer of bpf_struct_ops_link helps subsystems to distinguish them. This pointer will be used in the later patches to let the subsystem initiate a detachment on a link that was registered to it previously.

2024-02-22	selftests/bpf: Test case for lacking CFI stub functions.	Kui-Feng Lee	2	-0/+103
	Ensure struct_ops rejects the registration of struct_ops types without proper CFI stub functions. bpf_test_no_cfi.ko is a module that attempts to register a struct_ops type called "bpf_test_no_cfi_ops" with cfi_stubs of NULL and non-NULL value. The NULL one should fail, and the non-NULL one should succeed. The module can only be loaded successfully if these registrations yield the expected results.
