rename cancel_rearming_delayed_work() to cancel_delayed_work_sync()
Imho, the current naming of cancel_xxx workqueue functions is very confusing.
cancel_delayed_work()
cancel_rearming_delayed_work()
cancel_rearming_delayed_workqueue() // obsolete
cancel_work_sync()
This looks as if the first 2 functions differ in "type" of their argument
which is not true any longer, nowadays the difference is the behaviour.
The semantics of cancel_rearming_delayed_work(dwork) was changed
significantly, it doesn't require that dwork rearms itself, and cancels dwork
synchronously.
Rename it to cancel_delayed_work_sync(). This matches cancel_delayed_work()
and cancel_work_sync(). Re-create cancel_rearming_delayed_work() as a simple
inline obsolete wrapper, like cancel_rearming_delayed_workqueue().
