From: Yury Norov Date: Mon, 5 Sep 2022 23:08:18 +0000 (-0700) Subject: lib/cpumask: delete misleading comment X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=7102b3bb070fdf4580a05cbfc5ad3c0691dc4bf9;p=linux.git lib/cpumask: delete misleading comment The comment says that HOTPLUG config option enables all cpus in cpu_possible_mask up to NR_CPUs. This is wrong. Even if HOTPLUG is enabled, the mask is populated on boot with respect to ACPI/DT records.
