* -------------------- ----- ----------------------
* CURRENT PATCH LEVEL: 1 00158
* -------------------- ----- ----------------------
* 25 Apr 93 Bruce Evans Support new interrupt code (intr-0.1)
* Miscellaneous trivial functions, including many
* that are often inline-expanded or done in assembler.
* Unsupported device function (e.g. writing to read-only device).
* Unconfigured device function; driver not configured.
* Unsupported ioctl function.
* Unsupported system function.
* This is used for an otherwise-reasonable operation
* that is not supported by the current system binary.
* Return error for operation not supported
* on a specific object or file type.
* Generic null operation, always returns success.
* Definitions of various trivial functions;
* usually expanded inline rather than being defined here.
