LinuxLists.cc - kernel header separation

2003-09-02 19:17:33

Subject: kernel 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/
- *
- *******************************************************/
-
-/* When a driver supports a certain function, but the cdrom drive we are
- * using doesn't, we will return the error EDRIVE_CANT_DO_THIS. We will
- * borrow the "Operation not supported" error from the network folks to
- * accomplish this. Maybe someday we will get a more targeted error code,
- * but this will do for now... */

+/*******************************************************
+ * 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/
+ *
+ *******************************************************/
+
+/* When a driver supports a certain function, but the cdrom drive we are
+ * using doesn't, we will return the error EDRIVE_CANT_DO_THIS. We will
+ * borrow the "Operation not supported" error from the network folks to
+ * accomplish this. Maybe someday we will get a more targeted error code,
+ * but this will do for now... */
