* [SCSI] scsi_dh_rdac : decide whether to send mode select based on operating modeMoger, Babu2011-05-01
| | | | | | | | | | | | | | Based on the operating modes, handler decides whether to send mode select or not. Purpose here is to reduce io-shipping as much as possible whenever there is an option.

| | | | | | | | | | | | | | | | | | | This patch adds definitions to support for different operating modes for LSI rdac storage. Currently, rdac support 3 operation modes. 1. RDAC mode(legacy) 2.

* [SCSI] mpt2sas : WarpDrive New product SSS6200 support addedKashyap, Desai2011-05-01
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch has Support for the new solid state device product SSS6200 from LSI and relavent features w.r.t SSS6200. The major feature added in this driver is supporting Direct-I/O to the SSS6200 storage.There are some additional changes done to avoid exposing the RAID member disks to the OS and hiding/exposing drives based on the OEM Specific Flag in Manufacturing Page10 (this is required to handle specific changes in the SSS6200 firmware). Each and every changes are listed below. 1. Hiding IR related messages. For SSS6200, the driver is modified not to print IR related events. Even if the debugging is enabled the IR related messages will not be displayed. In some places if there is a need to display a message related to IR the string "IR" is replaced with string "DD" and the string "volume" is replaced with "direct drive". But the function names are not changed hence there are some places where the reference to volume can be seen if debug level is set. 2. Removed RAID transport support In Linux the user can retrieve RAID volume information from the sysfs directory. This support is removed for SSS6200. 3. Direct I/O support. The driver tries to enable direct I/O when a volume is reported to the driver by the firmware through IRCC events and the driver does this just before reporting to the OS, hence all the OS issued I/O can go through direct path if they can, The first validation is to see whether the manufacturing page10 flag is set to expose all drives always. If that is set, the driver will not enable direct I/O and displays the message "DDIO" is disabled globally as drives are exposed. The driver checks whether there is more than one volume in the controller, if so the direct I/O will be disabled globally for all volumes in the controller and the message displayed will be "DDIO is disabled globally as number of drives > 1. If retrieving number of PD is failed the driver will not enable direct I/O and displays the message Failure in computing number of drives DDIO disabled. If memory allocation for RAIDVolumePage0 is failed, the driver will not enable direct I/O and displays the message Memory allocation failure for RVPG0 DDIO disabled. If retrieving RAIDVolumePage0 is failed the driver will not enable direct I/O and displays the message Failure in retrieving RVPG0 DDIO disabled If the number of PD in a volume is greater than 8, then the direct I/O will be disabled. If any of individual drives handle retrieval is failed then the DD-IO will be disabled. If the volume is not RAID0 or if the block size is not 512 then the DD-IO will be disabled. If the volume size is greater than 2TB then the DD-IO will be disabled. If the driver is not able to find a valid stripe exponent using the configured stripe size then the DD-IO will be disabled When the DD-IO is enabled the driver will check every I/O request issued to the storage and checks whether the request is either READ6/WRITE6/READ10/WRITE10, if it is and if the complete I/O transfer is within a stripe size then the I/O is redirected to the drive directly instead of the volume. On completion of every I/O, if the completion is failure means if the reply is address reply with a reply frame associated with it, then the type of I/O will be checked, if the I/O is direct then the I/O will be retried to the volume once.

* [SCSI] fcoe: have fcoe log off and lport destroy before ndo_fcoe_disableVasu Dev2011-05-01
| | | | | | | | | | | | | | | | | | Currently fcoe interface cleanup is done after ndo_fcoe_disable and that prevents logoff going out to the peer, so this patch moves all netdev cleanup and its releasing inside fcoe_interface_cleanup to have log off before ndo_fcoe_disable disables the fcoe. This patch also fixes asymmetric rtnl locking around fcoe_if_destroy, as currently this function requires rtnl held by its caller and then have this func drops the lock, instead now don't have any processing under rtnl inside fcoe_if_destroy, this required moving few func to get build working again.

* [SCSI] libfc: rec tov value and REC_TOV_CONST units usages is incorrectVasu Dev2011-05-01
| | | | | | | | | | | | | | | | | | | | Added REC_TOV_CONST intent was to have rec tov as e_d_tov + 1s but currently it is e_d_tov + 1ms since e_d_tov is stored in ms unit. Also returned rec tov by get_fsp_rec_tov is in ms and this ms tov is used as-is with fc_fcp_timer_set expecting jiffies tov. Fixed this by having get_fsp_rec_tov return rec tov in jiffies as e_d_tov + 1s and then use jiffies tov w/ fc_fcp_timer_set. Also some cleanup, no need to cache get_fsp_rec_tov return value in local rec_tov at various places.

| | | | | | | | | | | | | | | | | | For the explicit unplugging, we'd prefer to kick things off immediately and not pay the penalty of the latency to switch to kblockd. So let blk_finish_plug() do the run inline, while the implicit-on-schedule-out unplug will punt to kblockd. Signed-off-by: Jens Axboe <jaxboe@fusionio.com>
| * block: cleanup the block plug helper functionsChristoph Hellwig2011-04-15
| | | | | | | | | | | | | | | | | | | | | | | | It's a bit of a mess currently. task->plug is being cleared and reset in __blk_finish_plug(), and blk_finish_plug() is testing for a NULL plug which cannot happen even from schedule() anymore since it uses blk_needs_flush_plug() to determine whether to call into this function at all. So get rid of some of the cruft. Signed-off-by: Jens Axboe <jaxboe@fusionio.com>
| * block, blk-sysfs: Use the variable directly instead of a function callLiu Yuan2011-04-13
| | | | | | | | | | | | | | | | | | | | | | | | In the function blk_register_queue(), var _dev_ is already assigned by disk_to_dev().So use it directly instead of calling disk_to_dev() again. Signed-off-by: Liu Yuan <tailai.ly@taobao.com> Modified by me to delete an empty line in the same function while in there anyway. Signed-off-by: Jens Axboe <jaxboe@fusionio.com>
