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 4.19-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-4.19 subdirectory.
If you, or anyone else, feels it should not be added to the stable tree,
please let <stable@xxxxxxxxxxxxxxx> know about it.
commit 95236c1eced1d6fc77c6ca992d2800824fc1c114

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.
