[dm-devel] [PATCH v4 10/11] libmultipath: don't try to set hwhandler if it is retained

Setting a device handler only works if retain_attached_hw_handler is 'no', or if the kernel didn't auto-assign a handler. If this is not the case, don't even attempt to set a different handler. This requires reading the sysfs "dh_state" path attribute. Signed-off-by: Martin Wilck --- libmultipa
