This is a question regarding the kernel symbol table.
I used the X macro like
static struct symbol_table functions= {
#include <linux/symtab_begin.h>
X(function1),
X(function2),
X(function3)
#include <linux/symtab_end.h>
};
register_symtab(&functions);
in the init_module routine to export function1 function2 etc to the kernel
symbol table
Then I loaded the module using insmod
When I do lsmod my module is listed
When I do ksyms the functions are shown
When I access the functions from another module it works
But my application require that I access the functions from within
the kernel. Specifically from kernel/drivers/block/ll_rw_blk.c and
the fucntion add_request.
When I try to compile the kernel it says that symbols function1 cannot
be located.
Is there any changes I need to do to the kernel make files ?
Is it possible to access symbols exported by modules inside the kernel ?
Some help on this is much appreciated
Thanx
Ravi
