Folks, in the discussion about preempt count consistency across kernel configurations: https://lore.kernel.org/r/20200914204209.256266093@xxxxxxxxxxxxx/ it was concluded that the usage of in_interrupt() and related context checks should be removed from non-core code. In the long run, usage of 'preemptible, in_*irq etc.' should be banned from driver code completely. This series addresses the target subsystem. Most of in_interrupt() usage is debugging. There is one function which either invokes wait_for_completion() or schedules a timer based on in_interrupt(). Sebastian
