linux-next: manual merge of the net-next tree with the jc_docs tree

From: Stephen Rothwell
Date: Mon Feb 06 2023 - 18:07:44 EST

Hi all,

Today's linux-next merge of the net-next tree got a conflict in:

Documentation/networking/device_drivers/ethernet/mellanox/mlx5.rst

between commit:

2abfcd293b79 ("docs: ftrace: always use canonical ftrace path")

from the jc_docs tree and commit:

f2d51e579359 ("net/mlx5: Separate mlx5 driver documentation into multiple pages")

from the net-next tree.

I fixed it up (I removed the file and applied the following merge fix
patch) and can carry the fix as necessary. This is now fixed as far as
linux-next is concerned, but any non trivial conflicts should be mentioned
to your upstream maintainer when your tree is submitted for merging.
You may also want to consider cooperating with the maintainer of the
conflicting tree to minimise any particularly complex conflicts.

Subject: [PATCH] fixup for "net/mlx5: Separate mlx5 driver documentation into multiple pages"

interacting with "docs: ftrace: always use canonical ftrace path"
