Re: Linux Kernel generic question (procedure queue)

 Hello everybody,
 Is it possible to insert
a specific procedure (among with it's args) to the
kernel scheduler? I know that we can just call
schedule(); when we wait for an asychronus input or
we can even insert an interrupt to the kernel queue,
but is it possible to queue a procedure?
not realy the same effect but you could use a tasklet and call
tasklet_schedule(&write_byte_tasklet);
where the  write_bytee tasklet is nothing else but your write_byte function.
 Just for understanding the problem better, I have
a function write_buff that calls write_byte.
Write_byte
function uses PPC gpio for implementing something like
an SPI interface. When we write a big file (e.x 1M),
the system will not respond to anything until the
transfer is done. I inserted "schedule();" every time
the write_byte is called so that the system will
accually perform some other tasks. So my question is
if I could insert write_byte function to the scheduler
queue in such a way to prevent this problem.
