[PATCH RT 1/6] kernel: softirq: unlock with irqs on

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



We unlock the lock while the interrupts are off. This isn't a problem
now but will get because the migrate_disable() + enable are not
symmetrical in regard to the status of interrupts.
