As my experience, in the application level we can use the combination of
signal() and alarm() to
implement some simple works ,such as doing some scheduled task at a certain
time, invoke some routine
after a certain time...Now one thing confused me.I thing in the kernel module
we can implement the same works.
And I have tried to use the queue_task(&Task, &tq_timer),but when i try to
"insmod", the LINUX will broken.
Who can tell why?And hoew to implement the combination of signal and alarm in
the Kenel Module?
Thank you in advance!
