* [SCSI] zfcp: Cleanup function parameters for sbal value.Swen Schillig2010-07-28
| | | | | | | | | | | | | A lot of functions require the amount of SBALs as one of their parameter which is most times invariable. Therefore remove this parameter and set the SBAL value explicitly if a non standard value is required. In addition the warning message "oversized data" is replaced with a BUG_ON() statement assuring the limits defined and requested by zfcp.

* [SCSI] zfcp: Remove SCSI device when removing unitChristof Schmitt2010-07-28
| | | | | | | | | | | | Configuring a LUN in zfcp, also creates a SCSI device. For consistency, it makes sense to remove the SCSI device when the LUN is deconfigured. Replace the flush_work with the call to scsi_remove_device: scsi_remove_device also takes the scan_mutex that synchronizes itself with any long running device discovery.

* [SCSI] zfcp: Use forced_reopen in terminate_rport_io callbackChristof Schmitt2010-07-28
| | | | | | | | | | | | | When running in non-NPIV mode, the port_reopen in terminate_rport_io might succeed even though the remote port is not available. If the same port connection is held open from another operating system, the reopen is only a virtual operation and might not hit the SAN. Fix this by changing the call to forced_reopen that forces a logout/login operation in the SAN.

* [SCSI] zfcp: Register SCSI devices after successful fc_remote_port_addChristof Schmitt2010-07-28
| | | | | | | | | | | | | | | | | | | | | When the successful return of an adisc is the final step to set the port online, the registration of SCSI devices might be omitted. SCSI devices that have been removed before (due to a short dev_loss_tmo setting) might not be attached again. The problem is that the registration of SCSI devices is done only after erp has finished. The correct place would be after the call to fc_remote_port_add to mimick the scan in the FC transport class. Change the registration of SCSI devices to be triggered after the fc_remote_port_add call. For the initial inquiry command to succeed, the unit must also be open. If the unit reopen is still pending, the inquiry command to the LUN will be deferred with DID_IMM_RETRY, so there is no harm from this approach.

* [SCSI] sd: add support for runtime PMAlan Stern2010-07-28
| | | | | | | | | | | | | | | | This patch (as1399) adds runtime-PM support to the sd driver. The support is unsophisticated: If a SCSI disk device is mounted, or if its device file is held open, then the device will not be runtime-suspended; otherwise it will (provided userspace gives permission by writing "auto" to the sysfs power/control attribute). In order to make this work, a dev_set_drvdata() call had to be moved from sd_probe_async() to sd_probe(). Also, a few lines of code were changed to use a local variable instead of recalculating the address of an embedded struct device.

* [SCSI] implement runtime Power ManagementAlan Stern2010-07-28
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch (as1398b) adds runtime PM support to the SCSI layer. Only the machanism is provided; use of it is up to the various high-level drivers, and the patch doesn't change any of them. Except for sg -- the patch expicitly prevents a device from being runtime-suspended while its sg device file is open. The implementation is simplistic. In general, hosts and targets are automatically suspended when all their children are asleep, but for them the runtime-suspend code doesn't actually do anything. (A host's runtime PM status is propagated up the device tree, though, so a runtime-PM-aware lower-level driver could power down the host adapter hardware at the appropriate times.) There are comments indicating where a transport class might be notified or some other hooks added. LUNs are runtime-suspended by calling the drivers' existing suspend handlers (and likewise for runtime-resume). Somewhat arbitrarily, the implementation delays for 100 ms before suspending an eligible LUN. This is because there typically are occasions during bootup when the same device file is opened and closed several times in quick succession. The way this all works is that the SCSI core increments a device's PM-usage count when it is registered. If a high-level driver does nothing then the device will not be eligible for runtime-suspend because of the elevated usage count. If a high-level driver wants to use runtime PM then it can call scsi_autopm_put_device() in its probe routine to decrement the usage count and scsi_autopm_get_device() in its remove routine to restore the original count. Hosts, targets, and LUNs are not suspended while they are being probed or removed, or while the error handler is running. In fact, a fairly large part of the patch consists of code to make sure that things aren't suspended at such times.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | Issue description: In multipath topology, when device deletion is in transient state, multipath driver can call blk_flush_queue() as part of path failure. Before device get deleted from OS, Device may go OFFLINE as part of error handling kicked off triggered from multipathing driver. Above condition hits more frequently if device missing delay timer (which is LSI specific firmware parameter) is non zero value. root cause of this issue is Error handling thread is getting kicked off for device which is not really present(in transient state of deleting). This patch has solution for this issue. driver is now using eh_timed_out callback. See below. mptsas_transport_template->eh_timed_out = mptsas_eh_timed_out Using mptsas_eh_timed_out function, driver can decide weather vdevice is under Device missing delay or deleting state. for either of those cases, there is BLK_EH_RESET_TIMER return to scsi mid and error handling thread will not be kicked off for that particular scsi command.
