SubjectRe: [PATCH, RFC] random: introduce getrandom(2) system call
Hey Ted, one more nit. Yes, I have a bicycle too..

I see here we add a flag to make it block - whereas it seems most
other system calls that can block the flag is
added to make it not block (I.E. O_NONBLOCK, etc. etc.) Would it make
more sense to invert this so it was more
like the typical convention in other system calls?
