high resolution timers and timer interrupt thrashing

[Sudharsan Vijayaraghavan]

Hi All,

With CONFIG_HIGH_RES_TIMERS configured and a whole lot of timer_create with
interval of less than jiffy (i.e., few nano seconds) we are bound to
get timer interrupts
less than a jiffy because set_next_event will configure for expires
less than jiffy.

This means we are thrashing the system with more timer interrupts,
perhaps to extent
of almost every clock tick, is my understanding correct?

Given this is it not dangerous to configure CONFIG_HIGH_RES_TIMERS
Please give your thoughts

Thanks,
Sudharsan
