+ 05/27/04
+ Bob Russell
+ - updated target/README to explain how to add/delete files, and how to
+   associate target numbers and lun numbers between initiator and target.
+ - lots of changes to target/scsi_target.{c,h}:
+ - reorganized mapping of target_id and lun numbers to use a new table called
+   target_map_table[][] containing MAX_TARGETS * MAX_LUNS elements, each
+   element is of type target_map_item.  Also added a mutex semaphore called
+   target_map_sem to control access to this table.  This new table replaces
+   the old scsi_device[][] and target_info[][] tables, the old fdlist, and the
+   old devset_t type.
+ - eliminated global target_num and replaced it with static target_count in
+   scsi_target.c, since the number of targets no longer has to be one more
+   than the largest target_id.
+ - added global target_in_use() to iscsi_common.h, with definitions in
+   initiator/iscsi_initiator.c and target/scsi_target.c.
+ - added addfile and delfile commands (and add_file(), del_file() functions) to
+   FILEIO mode so that files can be dynamically added to or removed from
+   target_map table.  These are based on changes provided by Bjorn Thordarson
+   -- thanks Bjorn.
+ - in several places, added info to messages that indicates operating mode
+   (MEMORYIO, DISKIO, FILEIO, GENERICIO) of the scsi_target module.
+ - added cmd_queue_lock spinlock to target_data structure to replace queue_sem
+   as the control lock for the cmd_queue, which is now a generic list_head list.
+ - added allocate_report_lun_space() to consolidate code dealing with REPORT_LUNS
+   commands in the different modes.  Much more consolidation of common code
+   needs to be done!
+ - moved dump_buffer() from initiator/initiator_utilities.c to
+   common/lun_packing.c so target could use it too.
+ 
+ 04/25/04
+ Bob Russell
+ - fixed printing of function and line in TRACE printing.
+ - added some minor debug printing in iscsi_target.c
+ 
+ 04/08/04
+ Bob Russell
+ - eliminated a race condition in target in which R2Ts were being sent with
+   ExpCmdSN set to the CmdSN of the command that generated them
+   (should be CmdSN + 1).
+ 
+ 04/04/04
+ Bob Russell
+ - in text_param.c, fixed bug in parsing of, and reporting errors about,
+   the target number at the end of the TargetName string.
+ - in common and initiator subdirectories, cleaned up code by adding
+   TRACE_WARNING and calls to it.  Also slightly changed wording in some
+   ERROR messages.
+ - in common subdirectory, cleaned up code by adding
+   print_bad_security_key() and print_not_allowed_security_key() and calls
+   to them.
+ - in scsi_target.{c,h}, fixed race condition on access to command queue.
+   Replaced coded-out cmd_queue_start and cmd_queue_end list with generic
+   "struct list_head cmd_queue", eliminated queue_sem semaphore, replaced
+   add_delete spinlock with cmd_queue_lock spinlock, and used cmd_queue_lock
+   to control all access to the cmd_queue.  Also eliminated some unnecessary
+   searches on the cmd_queue.
+ - in scsi_target.c, added a test before all up() on target_data.target_sem 
+   so that the up() is done only if the semaphore is not already unlocked
+   (to preserve the semantics of a binary rather than a counting semaphore).
