This is a note to let you know that I've just added the patch titled eth: remove copies of the NAPI_POLL_WEIGHT define to the 5.4-stable tree which can be found at: http://www.kernel.org/git/?p=linux/kernel/git/stable/stable-queue.git;a=summary The filename of the patch is: eth-remove-copies-of-the-napi_poll_weight-define.patch and it can be found in the queue-5.4 subdirectory. If you, or anyone else, feels it should not be added to the stable tree, please let <stable@xxxxxxxxxxxxxxx> know about it. commit 8ebaa6f8b0f75d7e11a78076dd740fd1571ac938 Author: Jakub Kicinski <kuba@xxxxxxxxxx> Date: Thu Apr 28 14:23:09 2022 -0700 eth: remove copies of the NAPI_POLL_WEIGHT define [ Upstream commit 5f012b40ef639343a976553bf3cc26dd0474756e ] Defining local versions of NAPI_POLL_WEIGHT with the same values in the drivers just makes refactoring harder. Drop the special defines in a bunch of drivers where the removal is relatively simple so grouping into one patch does not impact reviewability.
