hi all,
i am using kernel 2.6.11.1 & implementing timers struct timer_list to introduce the delay between successive acknowledgements! i have declared the static struct timer_list * my_timer as local in tcp_send_ack function defined in tcp_output.c.
i have allocated the memory for struct timer_list using kmalloc. some portion of the code for timer_list is as follows:
my_timer->expires = jiffies + .01 * HZ
my_timer->data = "">
my_timer->function = (void *)my_function
the function (my_function)which i want to execute is tcp_transmit_skb which is called in the function my_function.
now when i recompile the kernel for the first step i.e make all
i get errors after

is it necessary to allocate the memory for the timer_list & free it?
where i am going wrong!
pls help me on this!
