Many user space API headers are missing licensing information, which makes it hard for compliance tools to determine the correct license. By default are files without license information under the default license of the kernel, which is GPLV2. Marking them GPLV2 would exclude them from being included in non GPLV2 code, which is obviously not intended. The user space API headers fall under the syscall exception which is in the kernels COPYING file: NOTE! This copyright does *not* cover user programs that use kernel services by normal system calls - this is merely considered normal use of the kernel, and does *not* fall under the heading of "derived work". otherwise syscall usage would not be possible. Update the files which contain no license information with an SPDX license identifier. The chosen identifier is 'GPL-2.0 WITH Linux-syscall-note' which is the officially assigned identifier for the Linux syscall exception. SPDX license identifiers are a legally binding shorthand, which can be used instead of the full boiler plate text. This patch is based on work done by Thomas Gleixner and Kate Stewart and Philippe Ombredanne. See the previous patch in this series for the methodology of how this patch was researched.

/*******************************************************
|
|
* As of Linux 2.1.x, all Linux CD-ROM application programs will use this
|
|
* (and only this) include file. It is my hope to provide Linux with
|
|
* a uniform interface between software accessing CD-ROMs and the various
|
|
* device drivers that actually talk to the drives. There may still be
|
|
* 23 different kinds of strange CD-ROM drives, but at least there will
|
|
* now be one, and only one, Linux CD-ROM interface.
|
|
*
|
|
* Additionally, as of Linux 2.1.x, all Linux application programs
|
|
* should use the O_NONBLOCK option when opening a CD-ROM device
|
|
* for subsequent ioctl commands. This allows for neat system errors
|
|
* like "No medium found" or "Wrong medium type" upon attempting to
|
|
* mount or play an empty slot, mount an audio disc, or play a data disc.
|
|
* Generally, changing an application program to support O_NONBLOCK
|
|
* is as easy as the following:
|
|
* - drive = open("/dev/cdrom", O_RDONLY);
|
|
* + drive = open("/dev/cdrom", O_RDONLY | O_NONBLOCK);
|
|
* It is worth the small change.
|
|
*
|
|
* Patches for many common CD programs (provided by David A. van Leeuwen)
|
|
* can be found at: ftp://ftp.gwdg.de/pub/linux/cdrom/drivers/cm206/
