CLOCK_REALTIME_RES and nanosecond resolution

[Benjamin Herrenschmidt]

Hi !

I noticed that we set

#define CLOCK_REALTIME_RES TICK_NSEC  /* In nano seconds. */

Unconditionally in kernel/posix-timer.c

Doesn't that mean that we'll advertise to userland (via clock_getres) a
resolution that is basically HZ ? We do get at lenght to get more
precise (up to ns) resolution in practice on many architectures but we
don't expose that to userland at all. Is this normal ?

Ben.
