Brian Behlendorf 429fe89cee Consistently use local_irq_disable/local_irq_enable ... It was observed that spl_kmem_cache_alloc() uses local_irq_save() and saves the interrupt state in a local variable. This would normally be fine except that spl_kmem_cache_alloc() calls spl_cache_refill() which re-enables interrupts. It is then possible that while interrupts are enabled the process is rescheduled to a different cpu before being disable again. This could result in us restoring the saved interrupt state from one cpu to another. What the consequences of this are aren't perfectly clear, but this is clearly a bug and it has the potential to cause issues. The code has been updated to just use local_irq_enable() and local_irq_disable() to avoid this. Signed-off-by: Brian Behlendorf <behlendorf1@llnl.gov>		2013-10-09 14:00:56 -07:00
