[S390] qdio: prevent call trace if CHPID is offline

2010-02-09T08:46:23+00:00

If a CHPID is offline during a device shutdown the ccw_device_halt|clear
may fail and the qdio device stays in state STOPPED until the shutdown is
finished. If an interrupt occurs before the device is set to INACTIVE
the STOPPED state triggers a WARN_ON in the interrupt handler.
Prevent this WARN_ON by catching the STOPPED state in the interrupt
handler.

[S390] qdio: continue polling for buffer state ERROR

2010-02-09T08:46:23+00:00

Inbound traffic handling may hang if next buffer to check is in
state ERROR, polling is stopped and the final check for further
available inbound buffers disregards buffers in state ERROR.
This patch includes state ERROR when checking availability of
more inbound buffers.

[SCSI] zfcp: Report FC BSG errors in correct field

2010-02-08T19:40:17+00:00

The status FC_CTELS_STATUS_REJECT for all FC BSG errors is not
appropriate. Instead, report -EIO in the result field if there was a
problem in zfcp with the FC BSG request. If the request is good from
our point of view, report result 0, status FC_CTELS_STATUS_OK and let
userspace read the Accept or Reject from the payload (as documented in
scsi_bsg_fc.h).

[S390] zcrypt: Do not remove coprocessor for error 8/72

2010-01-27T09:12:49+00:00

In a case where the number of the input data is bigger than the
modulus of the key, the coprocessor adapters will report an 8/72
error. This case is not caught yet, thus the adapter will be taken
offline. To prevent this, we return an -EINVAL instead.

[S390] sclp_vt220: set initial terminal window size

2010-01-27T09:12:49+00:00

When opening a SCLP VT220 terminal, the terminal window size is not
initialized (defaults to zero).
Since the SCLP VT220 terminal supports only 80x24, explicitly set
the window size to prevent (n)curses applications from guessing
the default setting.

[SCSI] zfcp: Set hardware timeout as requested by BSG request.

2010-01-17T18:40:13+00:00

The hardware used with zfcp provides a timer for CT and ELS requests
instead of an abort capability for these commands. To correctly handle
the FC BSG timeouts, pass the timeout from the BSG requests to the
hardware.

[SCSI] zfcp: Introduce bsg_timeout callback.

2010-01-17T18:40:12+00:00

Introduce a zfcp callback for timeouts triggered from FC BSG.  With
zfcp, the underlying hardware cannot abort CT or ELS requests, so
there is nothing to do when the block layer timeout expires.  To avoid
interference with the block layer timeout, simply indicate that the
block layer timer should be reset. The timer running in the hardware
for the pending CT or ELS request will return the request when it
expires.
