Is it possible to create a proc entry under /proc/sys/kernel directly by create_proc_read_entry in the way shown below?
No longer.
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.
Use register_sysctl_table() for sysctls.
