This series of commits fixes a problem with closing l2cap connection if socket has unACKed frames. Due an to an infinite loop in l2cap_wait_ack the userspace process gets stuck in close() and then the kernel crashes with the following report:

Thanks for your work, but I'm afraid the 3.16-stable branch is no longer being maintained (as of today).
Want me to mark it EOL and remove it from the release table on kernel.org now?
I was about to send that patch myself, but you're welcome to do so.
Thanks again for all your assistance with releasing updates for 3.2 and 3.16 over the past 8 years.
Ben.
