In mddev_stack_new_rdev(), if the integrity profile check fails, it returns -ENXIO, which means "No such device or address". This is inaccurate and can mislead users. Change it to return -EINVAL.Fixes: c6e56cf6b2e7 ("block: move integrity information into queue_limits")Returning -ENXIO predates the above commit by many, many years. Changing the return value might break applications which rely on the original behavior. In case of a stacking failure, an appropriate message is logged and the function returns an errno. How is that misleading?
Thanks for your review, I will delete it in v3. -- Thanks, Nan
