DELETE_MODULE(2) Linux Programmer's Guide DELETE_MODULE(2)NAMEdelete_module - Delete a loadable module
SYNOPSIS
long sys_delete_module (const char *name_user, unsigned int flags,
const struct timespec *rqtp,
struct timespec *rmtp);
DESCRIPTIONdelete_module deletes a loadable module. name_user points to the module
name that is given by the userspace call to this system call. The flags
parameter specifies what actions to take upon module use. There are two
values for the flags parameter:
O_TRUNC
If flags is set to this and CONFIG_MODULE_FORCE_UNLOAD is turned
on, deletion can take place; otherwise, the function returns
EBUSY.
O_NONBLOCK
If the module is in use, CONFIG_MODULE_FORCE_UNLOAD is turned
on, the module refcount is non-zero, and O_TRUNC is also defined
for the flag, then deletion can take place; otherwise, the func‐
tion returns EWOULDBLOCK.
RETURN VALUEdelete_module returns 0 on success; otherwise, it returns one of the
errors listed in the "Errors" section.
ERRORS-EPERM The current user does not have administrator capabilities to
modify the modules.

-EINTR A signal interrupt occurred.
-ENOENT
An invalid module name was specified.
-EWOULDBLOCK
Other running modules are dependent on the specified module.
