Subject: [PATCH bpf-next v13 4/7] bpf: Copy map value using copy_map_value_long for percpu_cgroup_storage maps
Date: Wed,  7 Jan 2026 10:20:19 +0800	[thread overview]
Message-ID: <20260107022022.12843-5-leon.hwang@linux.dev> (raw)
In-Reply-To: <20260107022022.12843-1-leon.hwang@linux.dev>

Copy map value using 'copy_map_value_long()'. It's to keep consistent
style with the way of other percpu maps.

No functional change intended.
