    hrtimer: Make enqueue mode check work on RT · 0ab6a3dd
    Thomas Gleixner authored
    hrtimer_start_range_ns() has a WARN_ONCE() which verifies that a timer
    which is marker for softirq expiry is not queued in the hard interrupt base
    and vice versa.
    
    When PREEMPT_RT is enabled, timers which are not explicitely marked to
    expire in hard interrupt context are deferrred to the soft interrupt. So
    the regular check would trigger.
    
    Change the check, so when PREEMPT_RT is enabled, it is verified that the
    timers marked for hard interrupt expiry are not tried to be queued for soft
    interrupt expiry or any of the unmarked and softirq marked is tried to be
    expired in hard interrupt context.
