orangefs: handle zero size write in debugfs If we write zero bytes to this debugfs file, then it will cause an underflow when we do copy_from_user(buf, ubuf, count - 1). Debugfs can normally only be written to by root so the impact of this is low. Signed-off-by: Dan Carpenter <dan.carpenter@oracle.com> Signed-off-by: Mike Marshall <hubcap@omnibond.com>
