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.

CREATE_MODULE(2) Linux Programmer's Manual CREATE_MODULE(2)
create_module - create a loadable module entry
caddr_t create_module(const char *name, size_t size);
Note: No declaration of this function is provided in glibc headers; see NOTES.
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.
On success, returns the kernel address at which the module will reside. On error, -1 is returned and errno is set appropriately.
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).
This system call is present on Linux only up until kernel 2.4; it was removed in Linux 2.6.
create_module() is Linux-specific.
The create_module() system call is not supported by glibc. No declaration is provided in glibc headers, but, through a quirk of history,
glibc does export an ABI for this system call. Therefore, in order to employ this system call, it is sufficient to manually declare the
interface in your code; alternatively, you can invoke the system call using syscall(2).
