| * [SCSI] zfcp: Fix wka port processingSwen Schillig2009-07-302-7/+5
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Under certain conditions it is possible that a WKA port ist not opened within the expected timeframe of half a second. In this situation the WKA port remains in the state OPENING preventing any succeding request to open the port. This led to unrecoverable remote ports. Fixing this by always setting an appropriate WKA port status before leaving the function and removing the timeout value here since it's not needed here because the general timeout processing would deal with it if required.

| * [SCSI] zfcp: Recover from stalled outbound queueChristof Schmitt2009-07-301-1/+4
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Depending on interruptions on some storage systems, the complete channel can stall which looks like an outbound queue stall to Linux. When trying to acquire a free SBAL for a non-SCSI command, zfcp waits for 5 seconds for a free slot to appear. This is the right place to detect a queue stall: If the wait times out, we assume a stalled queue and try to recover this. The overall strategy should be to trigger the erp from specific events, and not try an overall escalation from one failed port to a full-blown queue recovery. If we manage to send a command, the status codes for this command or a timeout will trigger the right follow-on actions.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | If an action fails, retry it until the erp count exceeds the threshold. If there is something fundamentally wrong, the FSF layer will trigger a more appropriate action depending on the FSF status codes. The followup for successful actions is a different followup than retrying failed actions, so split the code two functions to make this clear.

| | | | | | | | | | | | | | | | | | | | | | | | The ELS ADISC and the GID_PN requests sent from zfcp fit into unchained FSF requests. Change the FSF allocation logic to use unchained requests whenever possible where everything fits in one SBAL.

| | | | | | | | | | | | | | | | | | To set a dasd online dasd_change_state is called twice. The first cycle will schedule initial analysis of the device, set the rc to -EAGAIN and will not touch the device state any more. The initial analysis will in turn call dasd_change_state to increase the state to the final DASD_STATE_ONLINE. If the dasd_change_state on the second thread outruns the other one both finish with the state set to DASD_STATE_ONLINE and the device refcount will be decreased by 2. Fix this by leaving dasd_change_state on rc == -EAGAIN so that the refcount will always be decreased by 1.

* [S390] Use del_timer instead of del_timer_syncMichael Holzheu2009-06-221-1/+1
| | | | | | | | | | | | | When syncing the sclp console queue, we call del_timer_sync() while holding the "sclp_con_lock" spinlock. This lock is also taken in the timer function "sclp_console_timeout". Therefore the sync version of del_timer() cannot be used here. Because the synchronous deletion of the timer is only needed in the suspend callback and in that case only one CPU is remaining and therefore it is not possible that the timer function is running in parallel, we can safely use del_timer() instead of del_timer_sync().

Basically what my patch does is to group list and a count of addresses into newly introduced structure netdev_hw_addr_list. This brings us two benefits: 1) struct net_device becames a bit nicer. 2) in the future there will be a possibility to operate with lists independently on netdevices (with exporting right functions).

| * | | s390: remove driver_data direct access of struct deviceGreg Kroah-Hartman2009-06-1611-104/+105
| | |/ | |/| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | In the near future, the driver core is going to not allow direct access to the driver_data pointer in struct device. Instead, the functions dev_get_drvdata() and dev_set_drvdata() should be used. These functions have been around since the beginning, so are backwards compatible with all older kernel versions. Thanks to Sebastian Ott <sebott@linux.vnet.ibm.com> for fixing a few typos in my original version of this patch.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Introduce the power management callbacks to the 3270 driver. On suspend the current 3270 view is deactivated and for non-console 3270 device the release callback is done. This disconnects the current tty / fullscreen application from the 3270 device. On resume the current view is reactivated, on the tty you get a fresh login. If the system panics before the 3270 device has been resumed, the ccw device for the 3270 console is reactivated with ccw_device_force_console.
