Subject: [PATCH bpf-next] bpf: Remove redundant assignment to smap->map.value_size
Date: Wed, 23 Mar 2022 15:36:26 +0800	[thread overview]
Message-ID: <20220323073626.958652-1-ytcoode@gmail.com> (raw)

The attr->value_size is already assigned to smap->map.value_size
in bpf_map_init_from_attr(), there is no need to do it again in
stack_map_alloc()
