The GTP PDP lookup helpers are shared by RCU-protected data and report paths and RTNL-protected control paths such as gtp_genl_new_pdp(). The helpers walk RCU hlists, but they do not currently pass the RTNL condition for the control-path lookups.
Pass lockdep_rtnl_is_held() to the PDP hlist iterators. Existing RCU-reader callers remain valid because the RCU-list macros also accept an active RCU read-side section; the added condition only documents the non-RCU protection already used by RTNL control paths.

You are awesome, thank you!

For the record, I think this patch was not OK.
PDP context hashtable is protected by the genl_mutex, not rtnl.
If I'm mistaken, please let know, thanks!
