[PATCH] hrtimer: export symbols

[PATCH] hrtimer: export symbols

[Stephen Hemminger]

I want to use the hrtimer's in the netem (Network Emulator) qdisc.
But the necessary symbols aren't exported for module use.

I second this request -- we would like to use hrtimers in SystemTap
modules.  The patch that Stephen provided would be sufficient for our
use as well.

I requested this a few months ago, and it was rejected on grounds that
the API was not yet stable enough for export.  I hope that now it has
had time to settle so that modules may use the new API.

Thanks,
