I expressed multiple times that I am unhappy with the raw_spinlock_t
which both want to keep. It is important to be future proof but at the
same time I am not sure if they know how many in-hardirq kmalloc() or
kfree() invocation we have as of today in PREEMPT_RT.
I also had a patch in my series to keep the lock/unlock path symmetrical
and it I think that I the only one that is missing it.
