Subject: Disabling an interrupt
Date: Tue, 01 Mar 2011 16:55:08 +0800	[thread overview]
Message-ID: <4D6CB46C.4040701@gmail.com> (raw)

Hi,

     It's long before when I want to enable/disable an interrupt, I call 
enable_irq()/disable_irq(). However, recently, I do that again. 
disable_irq() do nothing. I looked into the code and find disable_irq() 
is pointing to a empty function default_disable(). This change is 
started from 2.6.20.

     I want to know what should I do if I want to disable an interrupt now?

     Thanks.

Jacky
