Subject: RT, timers and CLOCK_REALTIME_HR

Hi,

I have one question about CLOCK_REALTIME_HR.
Before the rt patch I used to work with this clock. ie : hrtimers-support-3.1.1

With the rt patch it seems CLOCK_REALTIME_HR does not exist anymore !
Is this normal ?
The kernel speaks about that in arch/ia64/Kconfig
perhaps it should be removed !

I had a libtimers using this clock.

Is the good correction to say CLOCK_REALTIME_HR = CLOCK_REALTIME ?
I don't want to modify all my programs.

Yes, we removed it a while ago. Same for CLOCK_MONOTONIC_HR.

Yep.

Probably that's the best hack for you.
