While adding support for the BPF_F_CPU and BPF_F_ALL_CPUS flags, the data copying logic of the following percpu map types needs to be updated: * percpu_array * percpu_hash * lru_percpu_hash * percpu_cgroup_storage Following Andrii’s suggestion[0], this patch refactors the data copying logic by introducing two helpers: * `bpf_percpu_copy_to_user()` * `bpf_percpu_copy_from_user()` This prepares the codebase for the upcoming CPU flag support.
