scsi: libsas: fix ata xfer length

2017-03-20T13:45:08+00:00

The total ata xfer length may not be calculated properly, in that we do
not use the proper method to get an sg element dma length.

According to the code comment, sg_dma_len() should be used after
dma_map_sg() is called.

This issue was found by turning on the SMMUv3 in front of the hisi_sas
controller in hip07. Multiple sg elements were being combined into a
single element, but the original first element length was being use as
the total xfer length.

EH_NOT_HANDLED is the default case if no eh_timed_out method is
provided, so there is no need to supply it.

block: split scsi_request out of struct request

2017-01-27T22:08:35+00:00

And require all drivers that want to support BLOCK_PC to allocate it
as the first thing of their private data.  To support this the legacy
IDE and BSG code is switched to set cmd_size on their queues to let
the block layer allocate the additional space.

scsi:libsas: fix oops caused by assigning a freed task to ->lldd_task

2016-07-21T00:53:35+00:00

A freed task has been assigned to ->lldd_task when lldd_execute_task()
failed in sas_ata_qc_issue(), and access of ->lldd_task will cause an
oops:
