NAME

delete_module - Delete a loadable module

SYNOPSIS

long sys_delete_module (const char *name_user, unsigned int flags, const struct timespec *rqtp, struct timespec *rmtp);

DESCRIPTION

delete_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 function returns EWOULDBLOCK.

RETURN VALUE

delete_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.

-EFAULT

An invalid user_name value was specified.

-EINTR

A signal interrupt occurred.

-ENOENT

An invalid module name was specified.

-EWOULDBLOCK

Other running modules are dependent on the specified module.

-EBUSY
