* SCSI host lock push-downJeff Garzik2010-11-161-1/+3
| | | | | | | | | | | | | | | | | | | | | | | | | 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.

* Staging: keucr driver: fix uninitialized variable & proper memset lengthKonstantin Katuev2010-11-106-31/+31
| | | | | | | | | | | There was commented out transfer_flags initialization. And i think memset should fill entire structure, not only length of pointer to it. This makes the driver work properly now on my hardware. Signed-off-by: Konstantin Katuev <kkatuev@gmail.com> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>

| | | | | | | The usb tree renamed the USB storage defines to make more sense, so this driver needs the changes as well so that things will compile properly. Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>

| | | | | | | | | The other part of keucr lost usb disconnect. Unplug SDcard after thread scan,the wrong rule in usb_stor_port_reset, so the driver still fail in stress test. Signed-off-by: Al Cho <acho@novell.com> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>
