Check for core ioctl and return ioctl permission flags
Synopsis
bool drm_ioctl_flags ( | unsigned int nr, |
| | unsigned int * flags); |
Arguments
nr
ioctl number
flags
where to return the ioctl permission flags
Description
This ioctl is only used by the vmwgfx driver to augment the access checks
done by the drm core and insofar a pretty decent layering violation. This
shouldn't be used by any drivers.
Returns
True if the nr corresponds to a DRM core ioctl numer, false otherwise.
