It conflicts with your new code. We can have an argument on whether IB should follow how SSB is being handled. Before that is settled,Thank you for the information.
It conflicts but I think users who read the below document get confused.
Especially, seccomp users must know the difference of this implicit specification
because both IB and SSB are force disabled simultaneously when seccomp is enabled
without SECCOMP_FILTER_FLAG_SPEC_ALLOW on x86.
