Sounds good. I have asked Yury to do that just that and change the
patches according to the current reviews without testing them with a
newer version of glibc.   Note getting consensus would be nice soon as
possible so I can start working again on glibc patches and make sure
the changes that are made to support a slightly different ABI on the
userland side is ok with them.

Thanks,
Andrew
