Create proc entry under /proc/sys/kernel

[RuoMu Hu <huruomu@gmail.com>]

Hi!

Is it possible to create a proc entry under /proc/sys/kernel directly by
create_proc_read_entry in the way shown below?

test_pde = create_proc_read_entry("/proc/sys/kernel/test", 0, NULL,
                                    test_read_proc, NULL);
if (test_pde == NULL) {
    printk(KERN_ERR "Failed to create the test proc file.\n");
    return -ENOMEM;
}

I'm using this in my kernel module but create_proc_read_entry always
returns fail, while there's no problem creating proc entries directly
under /proc.  The kernel source I'm building my kernel module against is
2.6.25.4.

Any idea?


Thanks
Romu
