Subject: bpf: cgroup: annotate pointers in struct cgroup_bpf with __rcu
X-Git-Url: http://git.cdn.openwrt.org/?a=commitdiff_plain;h=dcdc43d6642c828fa10d25130a92b712003d2ca4;p=openwrt%2Fstaging%2Fblogic.git

bpf: cgroup: annotate pointers in struct cgroup_bpf with __rcu

The member 'effective' in 'struct cgroup_bpf' is protected by RCU.
Annotate it accordingly to squelch a sparse warning.
