* SCSI host lock push-downJeff Garzik2010-11-161-3/+4
| | | | | | | | | | | | | | | | | | | | | | | | | Move the mid-layer's ->queuecommand() invocation from being locked with the host lock to being unlocked to facilitate speeding up the critical path for drivers who don't need this lock taken anyway. The patch below presents a simple SCSI host lock push-down as an equivalent transformation. No locking or other behavior should change with this patch. All existing bugs and locking orders are preserved. Additionally, add one parameter to queuecommand, struct Scsi_Host * and remove one parameter from queuecommand, void (*done)(struct scsi_cmnd *) Scsi_Host* is a convenient pointer that most host drivers need anyway, and 'done' is redundant to struct scsi_cmnd->scsi_done. Minimal code disturbance was attempted with this change. Most drivers needed only two one-line modifications for their host lock push-down.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch fixes 3 bugs in vport create/delete. 1) Replace scsi_add_host() with scsi_add_host_with_dma() 2) Fix rmmod hang when there are vports configured. This is due to a race condition between the workqueue destroy in pci remove context and the vport delete works being handled. The fix is to use a counter to track the vport delete work, so that workqueue destroy will not be called until all configured vports are deleted from workqueue. 3) Fix rmmmod crash when there are PBC vport configured. PBC is not allowed to be deleted dynamically. However, if someone try to delete it, it leaves the vport is wrong state. The fix is to restore the vport back to original state when the attempt to delete pbc vport delete is failed.

* | | [SCSI] bfa: fix possible IO double completionJing Huang2010-07-271-0/+34
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | While processing the ioim in callback functions, the ioim is still in io_q. During this time, if the itnim goes offline, the ioim is requeued from itnim->io_q into itnim->delay_comp_q although the request is already completed. This results in requeing the ioim into the callback queue if the ioim is not freed by the time the ioim is requeued. This results in double completion of the ioim. To fix this, whenever a response is received from firmware for an ioim, deque it from io_q and enque to fcpim->comp_q. This will eliminate any possibility of itnim picking any ioim for which the response is already received.

But the size of this structure(164 bytes) is larger than the reserved RME buffer size(128 byes). The following changes reduce the size of the structure to be less than RME buffer size(128 bytes): - Remove the trunk and loop info from link_state structure, because both trunk and loop are not supported. - Combine qos_vc_attr and fcf into an union.
