* [SCSI] libsas: drop sata port multiplier infrastructureDan Williams2012-07-202-7/+0
| | | | | | | | | | On the way to add a new sata_device field, noticed that libsas is carrying port multiplier infrastructure that is explicitly disabled by sas_discover_sata(). The aic94xx touches the unused port_no, so leave that field in case there was some use for it.

* [SCSI] libsas: fix sas_discover_devices return code handlingDan Williams2012-07-201-27/+12

The result is random discovery failures depending on configuration. Calls to sas_ex_join_wide_port are the source of the trouble as its return value is errantly assigned to 'res'. Convert it to bool and stop returning its result up the stack.

| | | | | | | | | | | | | The strategy handlers may be called in places that are problematic for libsas (i.e. sata resets outside of domain revalidation filtering / libata link recovery), or problematic for userspace (non-blocking ioctl to sleeping reset functions). However, these routines are also called for eh escalations and recovery of scsi_eh_prep_cmnd(), so permit them as long as we are running in the host's error handler, otherwise arrange for them to be triggered in eh_context.

* [SCSI] fix eh wakeup (scsi_schedule_eh vs scsi_restart_operations)Dan Williams2012-07-201-0/+14
| | | | | | | | | | | | | | | | | | | | | | | | | Rapid ata hotplug on a libsas controller results in cases where libsas is waiting indefinitely on eh to perform an ata probe. A race exists between scsi_schedule_eh() and scsi_restart_operations() in the case when scsi_restart_operations() issues i/o to other devices in the sas domain. When this happens the host state transitions from SHOST_RECOVERY (set by scsi_schedule_eh) back to SHOST_RUNNING and ->host_busy is non-zero so we put the eh thread to sleep even though ->host_eh_scheduled is active. Before putting the error handler to sleep we need to check if the host_state needs to return to SHOST_RECOVERY for another trip through eh. Since i/o that is released by scsi_restart_operations has been blocked for at least one eh cycle, this implementation allows those i/o's to run before another eh cycle starts to discourage hung task timeouts.

* [SCSI] libata, libsas: introduce sched_eh and end_eh port opsDan Williams2012-07-2010-37/+134
| | | | | | | | | | | | | | | | | | | | When managing shost->host_eh_scheduled libata assumes that there is a 1:1 shost-to-ata_port relationship. libsas creates a 1:N relationship so it needs to manage host_eh_scheduled cumulatively at the host level. The sched_eh and end_eh port port ops allow libsas to track when domain devices enter/leave the "eh-pending" state under ha->lock (previously named ha->state_lock, but it is no longer just a lock for ha->state changes). Since host_eh_scheduled indicates eh without backing commands pinning the device it can be deallocated at any time. Move the taking of the domain_device reference under the port_lock to guarantee that the ata_port stays around for the duration of eh.

| | | | | | | | | | | | | | | | | | | | | | | | | Use blk_queue_dead() to test whether the queue is dead instead of !sdev. Since scsi_prep_fn() may be invoked concurrently with __scsi_remove_device(), keep the queuedata (sdev) pointer in __scsi_remove_device(). This patch fixes a kernel oops that can be triggered by USB device removal. See also http://www.spinics.net/lists/linux-scsi/msg56254.html. Other changes included in this patch: - Swap the blk_cleanup_queue() and kfree() calls in scsi_host_dev_release() to make that code easier to grasp. - Remove the queue dead check from scsi_run_queue() since the queue state can change anyway at any point in that function where the queue lock is not held. - Remove the queue dead check from the start of scsi_request_fn() since it is redundant with the scsi_device_online() check.
