[PATCH v4 0/3] net: unix: fix use-after-free

[Jason Baron <jbaron@akamai.com>]

Hi,

These patches are against mainline, I can re-base to net-next, please
let me know.

They have been tested against: https://lkml.org/lkml/2015/9/13/195,
which causes the use-after-free quite quickly and here:
https://lkml.org/lkml/2015/10/2/693.

Thanks,

-Jason
