ukl@octopus:~/gsrc/linux-2.6$ git show v2.6.29.1-rt8:kernel/spinlock.c | sed -n -e '357,376p'
unsigned long __lockfunc __spin_lock_irqsave_nested(raw_spinlock_t *lock, int subclass)
{
unsigned long flags;
local_irq_save(flags);
preempt_disable();
spin_acquire(&lock->dep_map, subclass, 0, _RET_IP_);
/*
* On lockdep we dont want the hand-coded irq-enable of
* _raw_spin_lock_flags() code, because lockdep assumes
* that interrupts are not re-enabled during lock-acquire:
*/
#ifdef CONFIG_LOCKDEP
LOCK_CONTENDED(lock, _raw_spin_trylock, _raw_spin_lock);
#else
_raw_spin_lock_flags(lock, &flags);
#endif
return flags;
}
EXPORT_SYMBOL(__spin_lock_irqsave_nested);
so this seems to be already included in 2.6.29.1-rt8. Where is it
missing?
Best regards
Uwe
