Thanks so much for the quick turn around!
So I dropped all the reverts you suggested, and applied this one
against 4.13-rc4, but I'm still seeing the problematic behavior.

While running reboot tests w/ a specific set of USB devices (and
slub_debug enabled), I found that once every few hours my device would
be crashed with a stack that looked like this:

xhci_disable_slot() is a helper for disabling a slot when a device
goes away or recovers from error situations. Currently, it checks
the corespoding virt-dev pointer and returns directly (w/o issuing
disable slot command) if it's null.
This is unnecessary and will cause problems in case where virt

xhci_disable_slot() is a helper for disabling a slot when a device

success when it sees a dead host. This is not the right way to go.
It should return error and let the invoker know that disable slot

If xhci_disable_slot() returns success, a disable slot command
trb was queued in the command ring. The command completion
handler will free the virtual device data structure associated
with the slot. On the other hand, when xhci_disable_slot()
returns error, the invokers should take the responsibil
xhci_disable_slot() allows the invoker to pass a command pointer
as paramenter. Otherwise, it will allocate one. This will cause
memory leak when a command structure was allocated inside of this
