Right, I was looking at the generic version.

Still, as I'm only changing tun.c where we know the call comes
from a syscall, I don't think the stack is a great issue.

Besides, for TX we already perform everything from the same stack
depth and the TX path isn't that much shallower compared to the
RX path.

Cheers,
