Question about rescheduling in interrupt context.

["Thomas P. Abraham" <omas_uclinux@hotmail.com>]

 

Hi,

 

I have a question regarding rescheduling in interrupt context.

 

In the book "Linux Kernel Development" by Robert Love, on page 73 it is mentioned that process switch should not be performed in interrupt context. But isn't ret_from_intr also part of the interrupt context. ( ret_from_intr calls schedule. ). Please let me know if I am missing something here.

 

Thanks for your help and time.

 

Regards,

Thomas
