scsi: isci: remove redundant initialization to 'bit'

Variable bit is initialized with a value that is never read and is being updated immediately after the initialization, hence the initialization is redundant and can be removed.

In preparation for unconditionally passing the struct timer_list pointer to all timer callbacks, switch to using the new timer_setup() and from_timer() to pass the timer pointer explicitly.

[SCSI] isci: Fix interrupt coalescing assumption of active TCs

2012-09-24T08:11:04Z

We always assign a dummy task context to a port in order to address a silicon issue. We have 4 ports per controller. So when idle, there are always exactly 4 TCs "active". The adaptive interrupt coalescing code uses number of active TCs to figure out the coalescing values. However, we never hit "0" TCs because of the 4 dummy TCs. Putting in fix so that we calculate this correctly. Reported-by: Dan Melnic Signed-off-by: Dave Jiang Signed-off-by: James Bottomley

[SCSI] isci: Allow SSP tasks into the task management path.

2012-09-24T08:11:04Z

This commit fixes a driver bug for SSP tasks that require task management in the target after they complete in the SCU hardware. The problem was manifested in the function "isci_task_abort_task", which tests to see if the sas_task.lldd_task is non-NULL before allowing task management; this bug would always NULL lldd_task in the SCU I/O completion path even if target management was required, which would prevent task / target manangement from happening. Note that in the case of SATA/STP targets, error recovery is provided by the libata error handler which is why SATA/STP device recovery worked correctly even though SSP handling did not.
