[SCSI] ipr: qc_fill_rtf() method should not store alternate status register

2013-06-26T18:11:30+00:00

The 'ctl' field of  the 'struct ata_taskfile' is not really dual purpose, i.e.
it is not intended  for storing the alternate status register (which is mapped
at the same address in the legacy IDE controllers) in the qc_fill_rtf() method.
No other 'libata' driver except 'drivers/scsi/ipr.c' stores the alternate status
register's value in the 'ctl' field of 'qc->result_tf', hence this driver should
not do this as well...

[SCSI] ipr: fix addition of abort command to HRRQ free queue

2013-04-06T10:23:18+00:00

The abort command issued by ipr_cancel_op() is being added to the wrong
HRRQ free queue after the command returns. Fix it by using the HRRQ
pointer in the ipr command struct itself.

[SCSI] ipr: ipr_test_msi() fails when running with msi-x enabled adapter

2013-04-06T09:30:40+00:00

Loading ipr modules failed(-22) with msi-x enabled adapter. In ipr_test_msi(),
We need to pass the first vector of msix vectors instead of using pdev->irq
to request_irq() when adapter enables msix feature.

[SCSI] ipr: Fix oops while resetting an ipr adapter

2013-02-24T08:24:48+00:00

When resetting an ipr adapter, we use scsi_block_requests to
block any new commands from scsi core, and then unblock after
the reset. When hotplug removing an adapter, we shut it down
and go through this same code, but we've seen issues with
scsi_unblock_requests running after the adapter's memory has
been freed. There is really no need to block/unblock when
the adapter is being removed, so this patch skips the
block/unblock and will immediately fail any commands that
happen to make it to queuecommand while the adapter is
being shutdown.
