What is your use case? If it is indeed necessary in your case, you can extend BPF_TABLE_SHARED with additional parameters similar to BPF_TABLE_PINNED.

I encountered this issue when trying to add an lpm_trie bpf shared table. Although I have implemented this function in a similar way as you described, my question is, since implementing this function is not difficult, why not add a specialized macro instead of having a fixed flag?

I would like to reuse the same macro name instead of adding a new macro. This has been the convention for bcc for a while.

As you mentioned, since there is a preference for using repetitive Macros, why not provide the flag as a parameter in the BPF_TABLE_SHARED macro? This is one of the points I'm curious about as well.
