linux 内核源代码

	* Make lpfc_sli_hba_setup() return negative error codes on error
	  and correct the comment left over in lpfc_fcp.c
	* Removed the lpfc_loadtime variable.
	* Put a space between all ifs and their open parens '('.
	* Change Studly_Caps LPFC_SCSI_BUF_t to struct lpfc_scsi_buf.
	* Fixed insmod hang after hardware error.
	* Relocated scsi_host alloc to before we enable the interrupt
	  handler
	* Add .tmp_versions directory to Makefile clean target.  This
	  directory is created in the 2.6.5+ build process (with Red Hat
	  kernels at least).
	* Changing phba->config to kmalloc lpfc_icfgparam and not
	  *phba->config. This is manifesting itself as a panic in
	  pci_release_region().
	* Fix for firmware download / board reset problem.
	* Integrated patch from Christoph Hellwig ([e-mail]) to
	  reorganize and cleanup lpfc_fcp.c
	* Don't abort commands immediately when there is an RSCN event to
	  give driver time to rediscover targets before the midlayer
	  retries the SCSI commands.

Changes from 20040604 to 20040614

	* Changed version number to 8.0.4
	* Removed lpfc_valid_lun function.
	* Added scsi_buf safety pool to address scsi_buf failures in
	  queuecommand under low memory conditions.  Allocations now come
	  from kmalloc initially, but if kmalloc fails, the allocation
	  comes from the safety pool.
	* Modified lpfc_slave_alloc to only set the scsi_device->hostdata
	  pointer if the driver has discovered the target.  This routine
	  always returns success now as well since no error ever occurs in
	  the alloc routine.
	* Mask only info and warning messages.  Print all error messages
	  irrespective of mask.
	* Removing lpfc_log_chk_msg_disabled()
	* Changed lpfc_printf_log to take struct lpfc_hba * directly
	  instead of a "board number".
	* Convert dma_sync_single to pci_dma_sync_single_for_{device/cpu}.
	* Implemented new style log messages. The message strings are now
	  embedded in the call to lpfc_printf_log.
	* Decreased FLOGI discovery timeout to 20 seconds.
	* On error in lpfc_pci_probe_one() return -1 and not 1.
	* Allow for board numbers that are not sequential, paving the way
	  for hotplug support.
	* scsi_add_host() can fail, so wrap it around in an if(). Also
	  initiate scsi_scan_host() after attaching the sysfs attributes.
	* lpfc_release_version is used only in lpfc_ct.c, so move it there
	  and mark it as static.
	* Removed lpfc_sleep_ms and replaced with mdelay or schedule calls
	  directly
	* Removed all (struct list_head *) casts from clkData-related list
	  handling in list_add, list_del macros.
	* Removed EXPORT_SYMBOLs.
	* Removed LPFC_MIN_QFULL and lpfc_qthrottle_up.
	* Replace LPFCSCSITARGET_t with struct lpfc_target.
	* Replace LPFCSCSILUN_t with struct lpfc_lun.
	* Remove unused struct declarations (fcPathId and fcRouteId) from
	  lpfc_scsi.h.
	* Rewrite use of FC transport attributes.
	* Fix crash when link is lost.  This was due to lpfc_delay_iodone
	  calling list_del on an object that was never put on a list.
	* Remove trailing spaces at the end of all lines.
	* Set MAX_FCP_TARGET to 256 from 0xff.  Set MAX_FCP_LUN and
	  MAX_FCP_CMDS to their decimal equivalents and updated
	  documentation.

Changes from 20040526 to 20040604

	* Changed version number to 8.0.3
	* Completed sysfs FC transport support.
	* Removed unused fields in SCSI LUN and SCSI Target structures:
	  void *pTargetProto; void *pTargetOSEnv; void *pLunOSEnv;
	* Modified list_for_each to list_for_each_entry. Modified
	  list_for_each_safe to list_for_each_entry_safe.
	* Remove lpfc_dfc.h file.
	* Changed pHba->phba, pCommand->pcmd
	* Changed plogi_ndlp -> plogindlp, pos_tmp->postmp, pRsp->prsp,
	  pCmd->pcmd
	* Changed pText -> ptext
	* Changed p_tmp_buff -> ptmpbuff
	* Changed pBufList -> pbuflist, pRsp -> prsp, pCmd -> pcmd
	* Changed *pos_tmp -> *postmp, *p_mbuf -> *pmbuf
	* Following changes are made to the SCSI fast path: Added
	  DMA_BUF_t member to the lpfc_scsi_buf_t.  This will reduce a
	  memory allocation in the scsi fast path.  Added check for
	  targetp == NULL in the scsi fast path.  Increased number of
	  scatter gather entries in lpfc_scsi_dma_ext to 4 from 3 and
	  changed the size of lpfc_scsi_dma_ext to 264
	* Fixing some missing static lpfc_nportdisc.c.
	* Reordered #include lines so that lpfc.h doesn't have to #include
	  other header files.
	* Remove lpfc_get_hba_sym_node_name() as a global EXPORT and make
	  it static.
	* Move struct clk_data definition from lpfc_hw.h to lpfc_sli.h.
	* Changed LPFC_IOCBQ_t to struct lpfc_iocbq.
	* Changed LPFC_SLI_RING_t to struct lpfc_sli_ring.
	* Changed LPFC_NODELIST_t to struct lpfc_nodelist.
	* Rearranged lpfc_nportdisc.c by moving state machine array
	  (lpfc_disc_action) and the one function that uses it,
	  lpfc_disc_state_machine, to the end of the file, removing the
	  need for the raft of prototypes at the top.
	* Changed LPFC_BINDLIST_t to struct lpfc_bindlist.
	* Removed lpfc_issue_ct_rsp(), lpfc_sleep(), lpfc_add_bind(),
	  lpfc_del_bind(), lpfc_sli_wake_mbox_wait() and
	  lpfc_sli_issue_mbox_wait().
	* Fixed a large number of overly-long lines.
	* Fixed some discovery problems: Introduced deferred ndlp removal
	  when in DSM to avoid panic when in nested DMSs Fix NportId
	  fffc01 handling to not relogin after LOGO fixed handling of LOGO
	  on PLOGI issue.
	* Changed SLI_CT_REQUEST to lpfc_sli_ct_request.
	* Changed NAME_TYPE to struct lpfc_name.
	* Changed lpfcCfgParam_t to struct lpfc_cfgparam.
	* Changed LPFC_STAT_t to struct lpfc_stats.
	* Changed HBAEVT_t to struct lpfc_hba_event.
	* Changed Studly_Caps lpfcHBA_t to struct lpfc_hba.
	* Removed no longer used tasklet_running flag.
	* Removing *PSOME_VAR typedefs and using SOME_VAR* directly.
	* Changing .use_clustering to ENABLE_CLUSTERING.
	* Modify lpfc_queuecommand to return SCSI_MLQUEUE_HOST_BUSY when
	  it can't queue a SCSI command.  Also, remove cmnds_in_flight
	  member of struct lpfcHBA for 2.6 kernels as it was only needed
	  to determine what to return from queuecommand.
	* Change return type of lpfc_evt_iocb_free to void as it doesn't
	  return anything.
	* Remove unused cmnd_retry_list and in_retry members in struct
	  lpfcHBA.
	* Remove some instances of unneeded casting of kmalloc's return in
	  lpfc_scsiport.c
	* Remove lpfc_linux_attach() and lpfc_linux_detach(). Integrate
	  them into lpfc_probe_one() and lpfc_release_one() respectively.
	* Remove lpfc_num_iocbs, lpfc_num_bufs module parameters
	* Remove #defines for NUM_NODES, NUM_BUFS and NUM_IOCBS

Changes from 20040515 to 20040526

	* Changing version number to 8.0.2.
	* Including dma-mapping.h as one of the include headers.  Also
	  rearrange the #include order.
	* Make functions static as appropriate.
	* queuecommand() will now return SCSI_MLQUEUE_HOST_BUSY instead of
	  1 to backpressure midlayer.
	* Removed function prototypes for lpfc_start_timer() and
	  lpfc_stop_timer()
	* Changed timer support to be inline.  Clk_data is now declared
	  right next to the corresponding timer_list entry so we don't
	  have to allocate these clk_data dynamically.
	* Add readls after writels to PCI space to flush the writes.
	* Fix misspelled word "safety" in function names.
	* Fix up comments in lpfc.conf for per HBA parameters to reflect
	  new implementation.
	* Change lpfc_proc_info handler to get the Nodename from
	  fc_nodename and not fc_portname.
	* Fix up some comments and whitespace in lpfc_fcp.c.
	* Formatting changes: get rid of leading spaces in code
	* Move discovery processing from tasklet to a kernel thread.
	* Move ndlp node from unmap list to map list if ADISC completed
	  successfully.
	* Flush all the ELS IOCBs when there is a link event.
	* LP9802 qdepth is twice the LP9802DC qdepth.  Delay
	  elx_sched_init after READ_CONFIG to get max_xri from the
	  firmware.  Reset ELX_CFG_DFT_HBA_Q_DEPTH to max_xri after
	  READ_CONFIG
	* Fix fc_get_cfg_parm() to be more robust and support embedded hex
	  values.  The lpfc_param's are now defined as:
	  lpfc_log_verbose="lpfc:0,lpfc0:0x10,lpfc1:4,lpfc100:0xffff" The
	  "," delimter does not matter. It can be anything or not exist at
	  all. ie param = "lpfc:0lpfc0:0x10.lpfc1:4txtlpfc100:0xffff" will
	  also work.  Additionally the string is treated as case
	  insensitive.
	* Changed all usage of lpfc_find_lun_device() to lpfc_find_lun().
	* Removed unnecessary wrappers lpfc_find_lun_device() and
	  lpfc_tran_find_lun().
	* Switch from using internal bus/id/lun to similar data from
	  scsi_device structure.
	* Eliminate one-line function lpfc_find_target()
	* Added slave_alloc, slave_destory
	* lpfc_scsi_cmd_start can now acquire lun pointer from
	  scsi_device->hostdata, which is setup in slave_alloc.
	* Eliminate unnecessary checking on every cmd just to see if we
	  are accessing the device the first time.
	* Remove assumption in lpfc_reset_lun_handler that a valid
	  lpfc_scsi_buf is hung off of linux's scsi_cmnd->host_scribble
	  when our reset is called.

Changes from 20040507 to 20040515

	* Changed version to 8.0.1
	* Fixed crash on driver rmmod after error injection tests and
	  lpfc_tasklet deadlock.
	* Modified lpfc.conf to remove limit on number of support hosts
	* Removed HBAAPI 
	* Removed duplication of SCSI opcodes from lpfc_fcp.h that are
	  available in scsi/scsi.h
	* Rework module_param usage
	* Added MODULE_PARAM_DESC for various module_params
	* Removed #define EXPORT_SYMTAB
	* Removed #includes of if_arp.h and rtnetlink.h
	* Removed string "Open Source" from MODULE_DESC
	* Cleanup duplicated string definitions used by MODULE_DESC
	* Renamed lpfc_pci_[detect|release] to lpfc_pci_[probe|remove]_one
	* Fix formatting of lpfc_driver
	* Remove unnecessary memset to 0 of lpfcDRVR
	* Attach driver attributes always unless pci_module_init failed
	* Remove all one-line wrappers from lpfc_mem.
	* Remove lpfc_sysfs_set_[show|store] as it is no longer needed
	* Redo lpfc_sysfs_params_[show|store] to one value per attribute rule
	* Breakdown lpfc_sysfs_info_show into smaller one value per attribute
	* Use device attributes instead of driver attributes where appropriate
	* Remove no longer needed EXPORT_SYMBOLs
	* Remove some unused code (1600 msg's related)

Changes from 20040429 to 20040507

	* Change version to 8.0.0
	* Fix the number of cmd / rsp ring entries in lpfc_fcp.c to match
	  the divisions setup in lpfc_hw.h.
	* Remove phba->iflag reference.
	* Several locking improvements.
	* Remove functions lpfc_drvr_init_lock, lpfc_drvr_lock,
	  lpfc_drvr_unlock and lpfc_hipri_*.
	* Remove LPFC_DRVR_LOCK and LPFC_DRVR_UNLOCK macros.
	* Make lpfc_info() use lpfc_get_hba_model_desc() instead of
	  rewriting almost identical code.
	* Fix 1 overly long line in each of lpfc_cfgparm.h, lpfc_ftp.c and
	  lpfc_sli.c.
	* Fix build for Red Hat 2.6.3 kernel by #defining MODULE_VERSION
	  only if it isn't already defined.
	* Change elx_sli_issue_mbox_wait to return correct error code to
	  the caller.
	* In some of the els completion routines, after calling
	  lpfc_elx_chk_latt, driver ignores the return code of the
	  lpfc_elx_chk_latt. This will prevent the discovery state machine
	  restarting correctly when there are link events in the middle of
	  discovery state machine running. Fix this by exiting discovery
	  state machine if lpfc_els_chk_latt returns a non zero value.
	* Removed MAX_LPFC_BRDS from lpfc_diag.h
	* Removed unused first_check.
	* Remove some unused fields and defines.
	* Change lpfc-param names to lpfc_param.
	* Add use of MODULE_VERSION macro for 2.6 kernels.
	* Shorten length of some of the comment lines to make them more
	  readable.
	* Move FCP_* definitions to their own header file, lpfc_fcp.h.
	* Remove unused prototypes from lpfc_crtn.h: fcptst, iptst,
	  lpfc_DELAYMS.
	* Remove duplicated prototypes from lpfc_crtn.h:
	  lpfc_config_port_prep, lpfc_config_port_post,
	  lpfc_hba_down_prep.
	* Removed some unused export_symbols.
	* Install driver files into */drivers/scsi/lpfc instead of
	  */drivers/scsi.

Changes from 20040426 to 20040429

	* Declared export symbol lpfc_page_alloc and lpfc_page_free
	* Changed lpfc version number to 6.98.3
	* Move the definition of MAX_LPFC_BRDS to the only header file
	  that uses it (lpfc_diag.h).
	* Change lpfc_sli_wake_iocb_wait to do a regular wake_up since
	  lpfc_sli_issue_iocb_wait now sleeps uninterruptible.
	* Replace list_for_each() with list_for_each_safe() when a list
	  element could be deleted.
	* Fix IOCB memory leak

Changes from 20040416 to 20040426

	* Change lpfc_config_
