Definitions for private use by the ossctl program. Everything defined in this file is likely to change without notice between OSS versions.
Note that thse ioctl calls are not for public use. They cannot be used by applications that are not part of the official OSS distribution.

This file defines ioctl codes 200 to 255 in the 'X' block. These codes may be reused for internal purposes by other OSSv4 implementations that don't use this file. Implementations based on the 'stock' OSS code can add their private use ioctl codes in this file. However in such case it's recommended to notify the OSS development community (4Front Technologies) so that the code can be marked as reserved in the official sources.
