From e881a172dac4d9ea3b2a1540041d872963c269bd Mon Sep 17 00:00:00 2001 From: Mike Christie Date: Thu, 15 Oct 2009 17:46:39 -0700 Subject: [SCSI] modify change_queue_depth to take in reason why it is being called This patch modifies scsi_host_template->change_queue_depth so that it takes an argument indicating why it is being called. This will be used so that if a LLD needs to do some extra processing when handling queue fulls or later ramp ups, it can do so. This is a simple port of the drivers setting a change_queue_depth callback. In the patch I just have these LLDs adjust the queue depth if the user was requesting it. Signed-off-by: Mike Christie [Vasu.Dev: v2 Also converted pmcraid_change_queue_depth and then verified all modules compile using "make allmodconfig" for any new build warnings on X86_64. Updated original description after combing two original patches from Mike to make this patch git bisectable.] Signed-off-by: Vasu Dev [jejb: fixed up 53c700] Signed-off-by: James Bottomley --- include/scsi/libiscsi.h | 3 ++- 1 file changed, 2 insertions(+), 1 deletion(-) (limited to 'include/scsi/libiscsi.h') diff --git a/include/scsi/libiscsi.h b/include/scsi/libiscsi.h index a72edd4ecee..2db2bc26b1e 100644 --- a/include/scsi/libiscsi.h +++ b/include/scsi/libiscsi.h @@ -333,7 +333,8 @@ struct iscsi_host { /* * scsi host template */ -extern int iscsi_change_queue_depth(struct scsi_device *sdev, int depth); +extern int iscsi_change_queue_depth(struct scsi_device *sdev, int depth, + int reason); extern int iscsi_eh_abort(struct scsi_cmnd *sc); extern int iscsi_eh_target_reset(struct scsi_cmnd *sc); extern int iscsi_eh_device_reset(struct scsi_cmnd *sc); -- cgit v1.2.3
