[S390] dcssblk: fix race in dcssblk_add_store() Concurrently adding the same segment may lead to duplicate device_register() calls, which will trigger an error in kobject code: "... don't try to register things with the same name in the same directory". This patch adds a check to avoid this. Signed-off-by: Gerald Schaefer <gerald.schaefer@de.ibm.com> Signed-off-by: Martin Schwidefsky <schwidefsky@de.ibm.com>
