Hi!
The objective of this series is to dump ethtool policies
to be able to tell which flags are supported by the kernel.
Ethtool policies are per command.
First patch here is included for completeness - it's already
in net, but other patches won't apply cleanly without it.
The series adds new set of "light" ops which don't have all
the callbacks, and won't have the policy. Most of families
are then moved to these ops. This gives us 4096B in savings
on an allyesconfig build (not counting the growth that would
have happened when policy is added):
text data bss dec hex
244415581 227958581 78372980 550747142 20d3bc06
244415581 227962677 78372980 550751238 20d3cc06
Next 5 patches deal the dumping per-op policy.
Jakub Kicinski (9):
genetlink: add missing kdoc for validation flags
genetlink: reorg struct genl_family
genetlink: add small version of ops
genetlink: move to smaller ops wherever possible
genetlink: add a structure for dump state
genetlink: use .start callback for dumppolicy
genetlink: bring back per op policy
genetlink: use per-op policy for CTRL_CMD_GETPOLICY
genetlink: allow dumping command-specific policy
