Hi,

Does anyone know how to create a timer in the kernel? I want to execute a
function after 1s and 3s and I want to create multiple instances of the
timer. The requirement here is to invoke a function after receiving a SYN
packet and then after 10s remove the perticular timer corresponding to that
SYN. This should be done for each SYN received.

Thanks,
Sadish.
