| | * [SCSI] zfcp: Add port_state attribute to sysfsSven Schuetz2008-07-121-0/+19
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The sysfs attribute /sys/class/fc_host/hostX/port_state was not set by zfcp so far. Now, the appropriate members of the fc_function_template struct are set during its initialziation. The first is a boolean to show the port state. The second is a function pointer to the function zfcp_get_host_port_state, which reads the port state from our adapter status bits and calls fc_host_port_state with the approriate port state afterwards.

| | * [SCSI] zfcp: receiving an unsolicted status can lead to I/O stallSwen Schillig2008-06-056-35/+32
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Processing of an unsolicted status request can lead to a locking race of the request_queue's queue_lock during the recreation of the used up status read request while still in interrupt context of the response handler. Detaching the 'refill' of the long running status read requests from the handler to a scheduled work is solving this issue. In addition, each refill-run is trying to re-establish the full amount of status read requests, which might have failed in earlier runs.

An overrun of the variables is neither detected nor treated. The file has to be read twice to make a meaningful statement, because only the differences of the values between the two reads can be used. A reset of the values can be achieved by writing to the attribute.

The driver used to wait on a waitqueue if no empty buffer was available. This could lead to a deadlock if the driver was called from non-schedulable context. So fix this. The write operation may fail now. It returns the number of characters accepted. put_char will never fail, since it writes characters to an intermediate buffer which gets flushed as soon as it is full. That means the driver now can busy wait if something is in the intermediate buffer and a write_string operation follows. Seems to be an acceptable compromise, since that shouldn't happen too often.
