Amol Grover ab48c14a44 bpf, devmap: Pass lockdep expression to RCU lists ... commit 485ec2ea9c upstream. head is traversed using hlist_for_each_entry_rcu outside an RCU read-side critical section but under the protection of dtab->index_lock. Hence, add corresponding lockdep expression to silence false-positive lockdep warnings, and harden RCU lists.
