[PATCH] block: Don't disable interrupts in trigger_softirq()

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

 



trigger_softirq() is always invoked as a SMP-function call which is
always invoked with disables interrupts.

Don't disable interrupt in trigger_softirq() because interrupts are
already disabled.
