Of course it looks like using the same data, but it seems there is no
reason to think it needs the same time: e.g. some timer or workqueue
could retrigger after it's supposed to be killed. Any additional
debugging/poisonning might help to see it earlier, so this should be
safer for your system, but, most probably this would show data from
the damaged side, so not necessarily very helpful.
We are not even sure skbuffs were directly affected by this or they
were incorrectly freed because of other structures beeing damaged?
IMHO, e.g. starting your system with limited memory should cause
faster memory reclaiming, and thus more often triggering of these bugs,
but of course I can be wrong.
