Subject: [PATCH 10/10] lib/cpumask: move some one-line wrappers to header file
Date:   Wed,  6 Jul 2022 10:42:53 -0700
Message-Id: <20220706174253.4175492-11-yury.norov@gmail.com>
In-Reply-To: <20220706174253.4175492-1-yury.norov@gmail.com>

After moving gfp flags to a separate header, it's possible to move some
cpumask allocators into headers, and avoid creating real functions.
