Subject: [PATCH 0/3] bitmap: introduce find_random_bit() and use in clocksource
Date: Wed, 4 Jun 2025 17:21:20 -0400 [thread overview]
Message-ID: <20250604212125.25656-1-yury.norov@gmail.com> (raw)
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()
