dear sir
i want to call my own function inside the kernel
after a fixed interval(i.e some kind of timer)
how to do that which function i have to use to
repeat the function
anather way is that making my own system call
which calls my function and
this sytem call is being access by a user
dear sir
i want to implement a timer inside the kernel
so that a specific function of mine is called after
certain period of time
how to implement that?
thanks in advance

dear sir,
I am unable to use the system call kill(pid,sig).I
have included the header file . I used it in
a module to kill a process. The module is compiling
properly but giving the following error while
inserting the module,
unresolved symbol kill()
I am unable to track the bug here.

which file and function inside the kernel (is
called) during the mounting of proc file system while
system startup.
Is it do_mount?
And in which function does the unmounting of the
proc file system
during shutdown
thanks

there is one my_own module
which i will insert whenever i like through
insmod.
thus when the module is loaded it will create a proc

now i want to send the structure variable of
task_struct
i.e p to the module from the kernel at point when the
execution passes
through forking a new process
