Subject: Re: [PATCH v6 0/3] implement getrandom() in vDSO

Hey folks,

Exciting development: one of the glibc maintainers, Adhemerval, has
written up the beginning of an implementation for this series:
https://github.com/zatrazz/glibc/commits/azanella/arc4random-vdso

I assume it'll continue to mature while this patch stews on the
list here. But so far in my testing, it works well, and the performance
boost is there and real. I've patched it into my system's glibc and am
daily driving it.
