Subject: [PATCH 07/14] cpumask: use cpumask_next_wrap() where appropriate
Date: Sat, 28 Dec 2024 10:49:39 -0800	[thread overview]
Message-ID: <20241228184949.31582-8-yury.norov@gmail.com> (raw)
In-Reply-To: <20241228184949.31582-1-yury.norov@gmail.com>

Now that cpumask_next{_and}_wrap() is wired to generic
find_next_bit_wrap(), we can use it in cpumask_any{_and}_distribute().

This automatically makes the cpumask_*_distribute() functions to use 
small_cpumask_bits instead of nr_cpumask_bits, which itself is a good
optimization.
