Operating Systems Linux SuSE max number of slabs per kernel module (kernel 2.6.17, suse) Post 302160513 by Brendan Kennedy on Tuesday 22nd of January 2008 03:59:18 AM

Thanks for the clarification Perderabo! I don't know why I got to thinking of slab spaces as 'zones'. I think I'll buy that book too...

I am aware that there is a limited amount of memory space, however is it not more efficient to use slabs (especially for allocations in the data path) since they result in less fragmentation and unused pages are reclaimed by the kernel anyway?

How to convert Linux Kernel built-in module into a loadable module

Hi all, I am working on USB data monitoring on Fedora Core 9. Kernel 2.6.25 has a built-in module (the one that isn't loadable, but compiles and links statically with the kernel during compilation) to snoop USB data. It is in <kernel_source_code>/drivers/usb/mon/. I need to know if I can... (0 Replies)

CREATE_MODULE(2)					     Linux Programmer's Manual						  CREATE_MODULE(2)

NAME
create_module - create a loadable module entry SYNOPSIS
#include <linux/module.h> caddr_t create_module(const char *name, size_t size); DESCRIPTION
Note: This system call is present only in kernels before Linux 2.6. create_module() attempts to create a loadable module entry and reserve the kernel memory that will be needed to hold the module. This sys- tem call requires privilege. RETURN VALUE
On success, returns the kernel address at which the module will reside. On error -1 is returned and errno is set appropriately. ERRORS
EEXIST A module by that name already exists. EFAULT name is outside the program's accessible address space. EINVAL The requested size is too small even for the module header information. ENOMEM The kernel could not allocate a contiguous block of memory large enough for the module. ENOSYS create_module() is not supported in this version of the kernel (e.g., the kernel is version 2.6 or later). EPERM The caller was not privileged (did not have the CAP_SYS_MODULE capability). VERSIONS
This system call is present on Linux only up until kernel 2.4; it was removed in Linux 2.6. CONFORMING TO
create_module() is Linux-specific. SEE ALSO
