Thanks for your backporting efforts. There is already a revert for this patch
queued up in batadv/net [1] (targets net.git). So maybe you want to drop this
patch from your stable queue.
We also got test results from Linus which showed that this problem didn't
happen anymore with recent kernel versions (without his patch). These results
made him also Ack the revert.
Sorry about this confusing situation.
Kind regards,
Sven
