JIRA: https://issues.redhat.com/browse/RHEL-23643 commit b460bc8302f222d346f0c15bba980eb8c36d6278 Author: Hou Tao <houtao1@huawei.com> Date: Fri Oct 20 21:31:57 2023 +0800 mm/percpu.c: introduce pcpu_alloc_size() Introduce pcpu_alloc_size() to get the size of the dynamic per-cpu area. It will be used by bpf memory allocator in the following patches. BPF memory allocator maintains per-cpu area caches for multiple area sizes and its free API only has the to-be-freed per-cpu pointer, so it needs the size of dynamic per-cpu area to select the corresponding cache when bpf program frees the dynamic per-cpu pointer.
