Agreed. Going by this version of function-granularity KASLR from 3 years
ago:

https://lwn.net/Articles/824307/
https://lwn.net/ml/linux-kernel/20200623172327.5701-1-kristen@linux.intel.com/

The fgKASLR feature looks entirely viable to me. Back then I presumed it
would get iterated beyond v3, and then it fell off my radar. :-/

If Kristen or someone else would like to dust this off & submit a fresh
version it would be much appreciated!

Thanks,

Ingo
