This patch syncs the scsi_id in the udev tree to version 0.5.
+2004-jun-23:
+ * scsi_id.h: increase MAX_SERIAL_LEN from 128 to 256, as some
+ devices (maybe broken ones) are giving really long id's.
+
+2004-jun-17:
+ * Makefile: Olaf Hering add spotless target (already in udev).
+
+2004-jun-17:
+ * scsi_serial.c: Include linux/compiler.h so we can build with
+ klibc using kernel headers.
+
+2004-may-24:
+ * scsi_id.c: Rename major and minor to maj min to avoid compiler
+ warnings when compiled with -D_GNU_SOURCE.
+
+2004-mar-30:
+ * scsi_id.config: Minor wording changes
+
+2004-mar-30:
+ * scsi_id.h: Don't supply a makedev() when built under klibc.
+
+2004-mar-30:
+ * scsi_id.c: Ken Brush <ken@cgi101.com> Have the command line
+ options override generic options.
+
+2004-mar-05:
+ * scsi_serial.c: Log INQUIRY failure, including the
+ failing page code and vpd values. And add a dprintf() to
+ the scsi_inquiry function.
+
+2004-mar-02:
+ * gen_scsi_id_udev_rules.sh: Per bug report from Atul Sabharwal
+ <atul.sabharwal@intel.com> change to not require that sysfs be
+ in the mount tab (and default to "/sys"), and fix so scsi_id
+ results containing spaces work correctly.
+
+2004-mar-02:
+ * scsi_id.8: Escape '-' with '\-'.
+
2004-feb-25:
* scsi_id.8: Add verbage about usage with udev, and running via
hotplug.

scsi_id is a program to generate a unique identifier for a given SCSI
device.

+It is primarily for use with the udev program key, or hotplug scripts that
+want persistent naming of scsi devices. It could also be used for
+automatic multi-path configuration or device mapper configuration.

+Version 0.5 requires:
- Linux kernel 2.6
- libsysfs 0.4.0
Major changes since the last release:
- - Support block device partitions
+ - Ken Brush <ken@cgi101.com> have the command line options
+ override generic options.
- - Added a script to auto-generate udev rules. The script is not
- installed but is part of the tarball.
+ - Fix the gen_scsi_id_udev_rules.sh to handle spaces in the id.
-Detailed changes:
+ - Don't supply a makedev() when built with klibc. Also, the
+ scsi_id supplied makedev() was using the old major/minor method.
- - Add man page verbage about usage with udev, and running via
- hotplug
+ - Include compiler.h so we can build against klibc, as recent sg.h
+ changes need a define for __user.
- - Disable support for -e (all output to stderr) as it cannot be
- used in any useful way, and the -c (device specific callout) as
- the code is incomplete and has no users.
+Other changes:
- - Don't print errno for NULL return from sysfs_get_classdev_device.
+ - Increase the MAX_SERIAL_LEN from 128 to 256, as some (possibly
+ broken devics) are returning very long id's
- - Get rid of dead/leftover code that checked if we are on a scsi
- bus.
+ - Add spotless target (via Olaf Hering's udev patch)
- - ":" consistently in output messages.
+ - minor wording changes in scsi_id.config
- - Add missing new lines for some error messages.
+ - Log INQUIRY failure, including the failing page code and vpd
+ values
- - open O_NONBLOCK so we handle tape drives without tapes loaded.
-
- - Remove hacks based on KLIBC define to get around problems when
- building with udev (udev libsysfs files were rearranged).
-
- - As done in udev code, support partitions via looking for a
- parent of the target path. Uses libsysfs functions to do most of
- the work, and includes changing a lot of variables to be struct
- sysfs_device instead of sysfs_class_device.
+ - Escape '-' with '\-' in the man page.
If a result is generated it is sent to standard output, and the program
exits with a zero value. If no identifier is output, the program exits
