FWIW, I am optimistic that this will take care of a number
of the use-after-free panics reported by syzbot (I have not
marked the patch with the recommended syzkaller Reported-by 
tags because I was not able to reproduce each original issue, 
but inspection of the traces suggests this missing patch may 
be behind the races that cause the reports).
