create_module - create a loadable module entry
caddr_t create_module(const char *name, size_t size);
Note: No declaration of this system call 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
system call requires privilege.
On success, returns the kernel address at which the module will reside. On
error, -1 is returned and errno is set to indicate the error.
This system call is present on Linux only up until kernel 2.4; it was removed in
create_module() is Linux-specific.
This obsolete system call is not supported by glibc. No declaration is provided
in glibc headers, but, through a quirk of history, glibc versions before 2.23
did export an ABI for this system call. Therefore, in order to employ this
system call, it was sufficient to manually declare the interface in your code;
alternatively, you could invoke the system call using syscall(2).

- A module by that name already exists.
- name is outside the program's accessible address space.
- The requested size is too small even for the module header
- The kernel could not allocate a contiguous block of memory large enough
for the module.
- create_module() is not supported in this version of the kernel
(e.g., the kernel is version 2.6 or later).
- The caller was not privileged (did not have the CAP_SYS_MODULE
