Instead of having to look in the kernel log for why an option was not correct just report the error to the user via the extack variable. What is currently reported today: ip link add bond0 type bond ip link set bond0 up ip link set bond0 type bond mode 4 RTNETLINK answers: Device or resource busy After this change: ip link add bond0 type bond ip link set bond0 up ip link set bond0 type bond mode 4 Error: unable to set option because the bond is up.

Also reduce the number of rtnl_unlock calls by just using the standard goto cleanup path.
