DESCRIPTION
The modldrv structure is used by device drivers to export driver spe‐
cific information to the kernel.
STRUCTURE MEMBERS
struct mod_ops *drv_modops;
char *drv_linkinfo;
struct dev_ops *drv_dev_ops;
drv_modops
Must always be initialized to the address of
mod_driverops. This member identifies the module as a
loadable driver.
drv_linkinfo
Can be any string up to MODMAXNAMELEN characters
(including the terminating NULL character), and is
