H A D | mesh_pathtbl.c | 30be52e4 Mon Nov 21 04:23:50 CST 2011 Johannes Berg <johannes.berg@intel.com> mac80211: fix RCU warnings in mesh
Sparse RCU checking reports two warnings in the mesh path table code. These are due to questionable uses of rcu_dereference.
To fix the first one, get rid of mesh_gate_add() and just make mesh_path_add_gate() do the correct deref.
To fix the second one, simply remove rcu_dereference() in mesh_gate_del() -- it already gets a proper pointer as indicated by the prototype (no __rcu annotation) and confirmed by the code.
