We are hitting a common bug were a timer is being triggered after it is
freed. This causes a corruption in the timer link list and crashes the
kernel. Unfortunately it is not easy to know what timer it was that was
freed. Looking at the code, it appears that there are several cases that
del_timer() is used when del_timer_sync() should have been.
Add a timer_shutdown_sync() that not only does a del_timer_sync() but will mark
the timer as terminated in case it gets rearmed, it will trigger a WARN_ON. The
timer_shutdown_sync() is more likely to be used by developers that are about to
free a timer, then using del_timer_sync() as the latter is not as obvious
to being needed for freeing. Having the word "shutdown" in the name of the
function will hopefully help developers know that that function needs to
be called before freeing.
The added bonus is the marking of the timer as being freed such that it
will trigger a warning if it gets rearmed. At least that way if the system
crashes on a freed timer, at least we may see which timer it was that was
freed.
There's some situations that already know that the timer is shutdown and
does not need to perform the synchronization (or can not due to its
context). For these locations there's timer_shutdown() that only shuts
down the timer (prevents it from being rearmed) but does not add checks if
the timer is currently running.
This code is taken from Thomas Gleixner's "untested" version from my
original patch and modified after testing and with some other comments
from Linus addressed. As well as some extra comments added.

Due to several bugs caused by timers being re-armed after they are
shutdown and just before they are freed, a new state of timers was added
called "shutdown". After a timer is set to this state, then it can no
longer be re-armed, and will trigger a warning if it is.
The following script was run to find all the trivial locations where
del_timer() or del_timer_sync() is called in the same function that the
object holding the timer is freed. It also ignores any locations where the
timer->function is modified between the del_timer*() and the free(), as
that is not considered a "trivial" case.
This was created by using a coccinelle script and the following commands:
$ cat timer.cocci
