However, Robert found more cases, and now it won't be as simple because we'd have to pass that down all the way to e.g. bond_do_ioctl() which isn't really feasible. Therefore, restore the old code. While looking at why SIOCGIFNAME was broken, I realized that Al had removed that case - which had been handled in an explicit separate function - as well, and looking through his work at the time I saw that bond ioctls were also affected by the erroneous removal. I've restored SIOCGIFNAME and bond ioctls by going through the (now renamed) dev_ifsioc() instead of reintroducing their own helper functions, which I hope is correct but have only tested with SIOCGIFNAME. ==================== Acked-by: Al Viro Signed-off-by: David S.
