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 --- drivers/message/fusion/mptscsih.h | 3 ++- 1 file changed, 2 insertions(+), 1 deletion(-) (limited to 'drivers/message/fusion/mptscsih.h') diff --git a/drivers/message/fusion/mptscsih.h b/drivers/message/fusion/mptscsih.h index e0b33e04a33b..45a5ff3eff61 100644 --- a/drivers/message/fusion/mptscsih.h +++ b/drivers/message/fusion/mptscsih.h @@ -128,7 +128,8 @@ extern int mptscsih_taskmgmt_complete(MPT_ADAPTER *ioc, MPT_FRAME_HDR *mf, MPT_F extern int mptscsih_scandv_complete(MPT_ADAPTER *ioc, MPT_FRAME_HDR *mf, MPT_FRAME_HDR *r); extern int mptscsih_event_process(MPT_ADAPTER *ioc, EventNotificationReply_t *pEvReply); extern int mptscsih_ioc_reset(MPT_ADAPTER *ioc, int post_reset); -extern int mptscsih_change_queue_depth(struct scsi_device *sdev, int qdepth); +extern int mptscsih_change_queue_depth(struct scsi_device *sdev, int qdepth, + int reason); extern u8 mptscsih_raid_id_to_num(MPT_ADAPTER *ioc, u8 channel, u8 id); extern int mptscsih_is_phys_disk(MPT_ADAPTER *ioc, u8 channel, u8 id); extern struct device_attribute *mptscsih_host_attrs[]; -- cgit v1.2.3
