Unfortunately further review highlighted risk for a critical race condition.
Hence this patch, despite fixing the reported NULL derefs, cannot be
submitted as is.
I am working on a new patch which I should be able to send to netdev for
review in one or two days.
Will report it here as soon as it's submitted.
Thank you.
