Hmm, a nanosecond value returned as integer? Is there a way to make
this a 64 bit return type, or is RET_INTEGER default to 64 bits in BPF
functions?

RET_INTEGER doesn't mean C 'int' width. It means non-pointer and
non-void value. The return value is always promoted to full
register width which is 64-bit.

OK.
