Zhengchao Shao says: ==================== net: refactor the walk and lookup hook functions in tc_action_ops The implementation logic of the walk/lookup hook function in each action module is the same. Therefore, the two functions can be reconstructed. When registering tc_action_ops of each action module, the corresponding net_id is saved to tc_action_ops. In this way, the net_id of the corresponding module can be directly obtained in act_api without executing the specific walk and lookup hook functions. Then, generic functions can be added to replace the walk and lookup hook functions of each action module. Last, modify each action module in alphabetical order. Reserve the walk and lookup interfaces and delete them when they are no longer used. This patchset has been tested by using TDC, and I will add selftest in other patchset. Last, thanks to Jamal Hadi Salim and Cong Wang for their advice. --- v3: remove hole from the structure tc_action_ops v2: save the net_id of each TC action module to the tc_action_ops structure ==================== Signed-off-by: David S.

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
