genetlink: make genl_ops flags a u8 and move to end
To save some space in the struct on 32-bit systems, make the flags a u8 (only 4 bits are used) and also move them to the end of the struct. This has no impact on 64-bit systems as alignment of the struct in an array uses up the space anyway. Signed-off-by: Johannes Berg <johannes.berg@intel.com> Signed-off-by: David S. Miller <davem@davemloft.net>
