Hello, i recently porting my driver from 2.4.35 to 2.6.X kernel.
I meet some strange behaviour with sema_init. This is the code snippet
/**
* this code is compiled & working in 2.4 kernel.
* Compiled in 2.6 but fail in module initialization.
*/
static struct semaphore sem_fail;
static init __init my_module_init_fail(void)
{
sema_init (&sem_fail, 1);
}
/**
* this code compiled & work in 2.6
*/
struct semaphore *sem;
static init __init my_module_init(void)
{
sem = (struct semaphore *) kmalloc (sizeof (struct semaphore
), GFP_KERNEL);
sema_init (sem, 1);
}
Any idea?
Thx
