In preparation for the patch that introduces the bpf_lookup_user_key() eBPF kfunc, move KEY_LOOKUP_ definitions to include/linux/key.h, to be able to validate the kfunc parameters.
Also, introduce key_lookup_flags_valid() to check if the caller set in the argument only defined flags. Introduce it directly in include/linux/key.h, to reduce the risk that the check is not in sync with currently defined flags.

Jarkko, could you please ack it if it is fine?
So, as said I'm not really confident that a function is even needed in the first place. It's fine if there are enough call sites to make it legit.
BR, Jarkko
