X-Git-Url: https://www.infradead.org/git/?a=commitdiff_plain;h=bd9d9b48eb1814ad761cce45774a18d95c33803c;p=users%2Fjedix%2Flinux-maple.git

bpf: Remove unused member rcu from bpf_struct_ops_map

The rcu member in bpf_struct_ops_map is not used after commit
b671c2067a04 ("bpf: Retire the struct_ops map kvalue->refcnt.")

Remove it.
