[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 <swen@vnet.ibm.com> Signed-off-by: Christof Schmitt <christof.schmitt@de.ibm.com> Signed-off-by: James Bottomley <James.Bottomley@suse.de>
