SCSI host lock push-down

2010-11-16T21:33:23+00:00

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.

drivers/staging: delete double assignment

2010-11-09T22:05:22+00:00

Delete successive assignments to the same location.  In three of the cases,
the two assignments are identical.  In the case of the file
rt2860/common/cmm_aes.c, the assigned variable i is never used, so both
assignments are dropped.

A simplified version of the semantic match that finds this problem is as
follows: (http://coccinelle.lip6.fr/)

// 
@@
expression i;
@@

*i = ...;
 i = ...;
//

Staging: hv: remove struct vmbus_channel_interface

2010-10-21T17:03:44+00:00

Now that no one uses this structure, remove it, and channel_interface.c
(which is now empty) and the function, vmbus_get_interface() which is
not needed anymore either.

2010-10-21T16:58:21+00:00

Drivers need to call this directly, so export it, like other
vmbus functions.
