Bug Description
After upgrading to the proposed kernel for Trusty (3.13.0-72.115) I cannot unlock a luks formatted usb drive. The cryptsetup process seems to hang with the following stack:

Looks like this kernel has a bad backport of upstream commit 2a708cff93f1 ("dm: fix AB-BA deadlock in __dm_destroy()").
To confirm this, I've uploaded a test kernel with this backport reverted:
