2014-03-27[SCSI] megaraid: simplify internal command handlingChristoph Hellwig4-150/+32
We don't use the passed in scsi command for anything, so just add a adapter- wide internal status to go along with the internal scb that is used unter int_mtx to pass back the return value and get rid of all the complexities and abuse of the scsi_cmnd structure. This gets rid of the only user of scsi_allocate_command/scsi_free_command, which can now be removed.

2014-03-27[SCSI] ses: Use vpd information from scsi_deviceHannes Reinecke1-28/+10

2014-03-27[SCSI] Add EVPD page 0x83 and 0x80 to sysfsHannes Reinecke4-1/+130
EVPD page 0x83 is used to uniquely identify the device. So instead of having each and every program issue a separate SG_IO call to retrieve this information it does make far more sense to display it in sysfs. Some older devices (most notably tapes) will only report reliable information in page 0x80 (Unit Serial Number). So export this in the sysfs attribute 'vpd_pg80'.

2014-03-19[SCSI] scsi_debug: prepare to enable clusteringAkinobu Mita1-50/+59
Currently, clustering support for scsi_debug is disabled. This is because there are for_each_sg() loops which assume that each sg list element is consisted with a single page. But enabling clustering support, each sg list element for scsi commands can be consisted with multiple pages. This replaces these for_each_sg() loops with sg mapping iterator which is capable of handling each sg list element is consisted with multiple pages.

SCSI devices may only be removed by calling scsi_remove_device(). That function must invoke blk_cleanup_queue() before the final put of sdev->sdev_gendev. Since blk_cleanup_queue() waits for the block queue to drain and then tears it down, scsi_request_fn cannot be active anymore after blk_cleanup_queue() has returned and hence the get_device()/put_device() pair in scsi_request_fn is unnecessary.

2014-03-15[SCSI] megaraid_sas: Performance boost fixes[email protected]2-9/+42
Host lock is added back around queuecommand. Host lock removal can create race conditon between ISR path(when RAID map update interrupt is raised) and IO build path of driver, since IO build path is making use of RAID map, and in case of RAID map update interrupt, old RAID map copy is memset to zero, which some IOs may be referencing in build IO path. Changes done for performance boost- 1) Added code to set SMP IRQ affinity per CPU. 2) Pass MSI-x index, while issuing sysPD IO.
