From 9e820afd0c4f3c8e8894aa91f5671fd7d11a787b Mon Sep 17 00:00:00 2001 From: Christof Schmitt Date: Tue, 13 Oct 2009 10:44:11 +0200 Subject: [PATCH] [SCSI] zfcp: Flush SCSI registration work when adding unit When configuring a LUN for use in zfcp, flush the SCSI work to ensure the SCSI device has been created before returning. This means that a configuration procedure can run these commands in a script and the SCSI device is available immediately after the unit_add: echo 1 > /sys/bus/ccw/drivers/zfcp/0.0.181d/online echo 0x401040C300000000 > \ /sys/bus/ccw/drivers/zfcp/0.0.181d/0x500507630313c562/unit_add lsscsi Reviewed-by: Swen Schillig Signed-off-by: Christof Schmitt Signed-off-by: James Bottomley --- drivers/s390/scsi/zfcp_sysfs.c | 1 + 1 file changed, 1 insertion(+) diff --git a/drivers/s390/scsi/zfcp_sysfs.c b/drivers/s390/scsi/zfcp_sysfs.c index 079a8cf518a3..d31000886ca8 100644 --- a/drivers/s390/scsi/zfcp_sysfs.c +++ b/drivers/s390/scsi/zfcp_sysfs.c @@ -224,6 +224,7 @@ static ssize_t zfcp_sysfs_unit_add_store(struct device *dev, zfcp_erp_unit_reopen(unit, 0, "syuas_1", NULL); zfcp_erp_wait(unit->port->adapter); + flush_work(&unit->scsi_work); zfcp_unit_put(unit); out: mutex_unlock(&zfcp_data.config_mutex);
