Hi everyone,
I am trying to prevent the ehci_hcd kernel module to load at boot time.
Here's what I've tried so far:
1) Add the following line to /etc/modprobe.d/blacklist.conf (as suggested here):

Hi all!
I am trying to register a device in an existing device class, but I am

I can create a class in a module, get the pointer to it and then use
it to register the device with:
*cl = class_create(THIS_MODULE, className);... (0 Replies)

Can someone tell me how to do this?
Just a thought that entered my mind when learning about structs.
First thought was:
struct one
{
struct two;
}
struct two
{
three;
}
one->two->three
would this be how you would access "three"? (1 Reply)

Hi All,
Is there a max number of slabs that can be used per kernel module? I'm having a tough time finding out that kind of information, but the array 'node_zonelists' (mmzone.h) has a size of 5. I just want to avoid buffer overruns and other bad stuff.
Cheers,

Hi
We are using a code generator for initializing structures with the #define macro. Compiling it with the GCC 2.8.1 (with -ansi) it OK. But when we are using the SUN C 5.0 compiler it screams.
Following is a code sample:
#include <stdlib.h>
#include <stdio.h>

INIT_MODULE(2) Linux Programmer's Manual INIT_MODULE(2)
NAME
init_module - initialize a loadable module entry
SYNOPSIS
#include <linux/module.h>
int init_module(const char *name, struct module *image);
DESCRIPTION
init_module() loads the relocated module image into kernel space and runs the module's init function.
The module image begins with a module structure and is followed by code and data as appropriate. The module structure is defined as fol-
lows:
struct module {
unsigned long size_of_struct;
struct module *next;
const char *name;
unsigned long size;
long usecount;
unsigned long flags;
unsigned int nsyms;
unsigned int ndeps;
struct module_symbol *syms;
struct module_ref *deps;
struct module_ref *refs;
int (*init)(void);
void (*cleanup)(void);
const struct exception_table_entry *ex_table_start;
const struct exception_table_entry *ex_table_end;
#ifdef __alpha__
unsigned long gp;
#endif
};
All of the pointer fields, with the exception of next and refs, are expected to point within the module body and be initialized as appro-
priate for kernel space, that is, relocated with the rest of the module.
This system call requires privilege.
RETURN VALUE
On success, zero is returned. On error, -1 is returned and errno is set appropriately.
ERRORS
EBUSY The module's initialization routine failed.
EFAULT name or image is outside the program's accessible address space.
EINVAL Some image slot is filled in incorrectly, image->name does not correspond to the original module name, some image->deps entry does
not correspond to a loaded module, or some other similar inconsistency.
ENOENT No module by that name exists.
EPERM The caller was not privileged (did not have the CAP_SYS_MODULE capability).
CONFORMING TO
init_module() is Linux-specific.
