    Subjectkernel header separation

    In a continuing series of "Things we should have done 5 years ago,
    do they really need to be done before the release of 2.6.0", here's a
    prototype of splitting the kernel headers into stuff we want userspace
    to see and stuff we don't.

    The basic principle is to put user headers in usr/include/linux and
    usr/include/asm-$(ARCH). Kernel headers may then include them as
    <user/foo.h> and <user-asm/foo.h>

    This patch implents the 4 lines of Makefile magic necessary and converts
    cdrom.h to use this split. Note that we can convert headers as slowly as
    we care to with this scheme.

    -/*******************************************************
    - * 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/

    +/*******************************************************
    + * 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/

    "It's not Hollywood. War is real, war is primarily not about defeat or
    victory, it is about death. I've seen thousands and thousands of dead bodies.

    In a continuing series of "Things we should have done 5 years ago,
    do they really need to be done before the release of 2.6.0", here's a
    prototype of splitting the kernel headers into stuff we want userspace
    to see and stuff we don't.

    The basic principle is to put user headers in usr/include/linux and
    usr/include/asm-$(ARCH). Kernel headers may then include them as
    <user/foo.h> and <user-asm/foo.h>

    This patch implents the 4 lines of Makefile magic necessary and converts
    cdrom.h to use this split. Note that we can convert headers as slowly as
    we care to with this scheme.

    -/*******************************************************
    - * 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/

    +/*******************************************************
    + * 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/

    "It's not Hollywood. War is real, war is primarily not about defeat or
