delete_module – Delete a loadable module

USAGE
       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 func-
              tion returns EWOULDBLOCK.

RETURN VALUE
       delete_module  returns  0  on success; otherwise, it returns one of the
       errors listed in the "Errors" section.

       -EWOULDBLOCK
