You mean list_for_each_entry_safe(c, next, &mrt->mfc_cache_array[i], list)
in mroute_clean_tables()?

Isn't this list just a member of struct mfc_cache?
I can't find the other codes in mroute_clean_tables uses this list
after unregister_netdevice_many.

Ok,I am fine if you drop this patch,just as commit ceaaec98ad99859ac90ac6863ad0a6cd075d8e0e
said "device is freed without touching its unreg_list". there will be no serious problems
if we don't have this patch.
