Most ethtool SET callbacks follow the same general structure. ethnl_parse_header_dev_get() rtnl_lock() ethnl_ops_begin() ... do stuff ... ethtool_notify() ethnl_ops_complete() rtnl_unlock() ethnl_parse_header_dev_put() This leads to a lot of copy / pasted code an bugs when people mis-handle the error path. Add a generic implementation of this pattern with a .set callback in struct ethnl_request_ops called to "do stuff". Also add an optional .set_validate which is called before ethnl_ops_begin() -- a lot of implementations do basic request capability / sanity checking at that point. Because we want to avoid generating the notification when no change happened - adopt a slightly hairy return values: - 0 means nothing to do (no notification) - 1 means done / continue - negative error codes on error Reuse .hdr_attr from struct ethnl_request_ops, GET and SET use the same attr spaces in all cases. Convert pause as an example (and to avoid unused function warnings). Signed-off-by: Jakub Kicinski <kuba@kernel.org> Signed-off-by: David S. Miller <davem@davemloft.net> |
