[PATCH 0/3] bitmap: introduce find_random_bit() and use in clocksource

Posted by Yury Norov 6 months, 2 weeks ago

From: Yury Norov [NVIDIA] <yury.norov@gmail.com>

nodemasks implement node_random(), which may also be useful for other
subsystems. Generalize the function, and propagate to cpumask API.

Yury Norov (3):
  bitmap: generalize node_random()
  cpumask: introduce cpumask_random()
  clocksource: improve randomness in clocksource_verify_choose_cpus()
