Re: [PATCH 0/2] [RFC] posix clock tuning

Recently on the lkml, we discussed how to allow adjustment of posix

If there is agreement on this approach, I will resubmit these two
patches as part of a longer series, including support for a new kind
of hardware clock, so you can see how it all fits together. But first,
I would like to concentrate on the new syscall itself.

The patches are against a recent net-next tree. Please don't worry if
the syscall tables are not quite up to date. I can fix that later.

Could you explain why the existing interfaces are not sufficient that do
what you describe?

man adjtime
man adjtimex
man clock_settime
?

Why would you need this to support a new hardware clock? You want the
clock to run at a different speed from system time?
