Apologies if I missed this...
It would be nice to see a description of the proposed syscall interface
in these changelogs! Then a few questions I have will be answered...
long trusted_for(const int fd,
const enum trusted_for_usage usage,
const u32 flags)
- `usage' must be equal to TRUSTED_FOR_EXECUTION, so why does it
exist? Some future modes are planned? Please expand on this.
- `flags' is unused (must be zero). So why does it exist? What are
the plans here?
- what values does the syscall return and what do they mean?
