[PATCH v2 stable-5.10.y stable-5.15.y] docs: futex: Fix kernel-doc references after code split-up preparation

[Salvatore Bonaccorso]

In upstream commit 77e52ae35463 ("futex: Move to kernel/futex/") the
futex code from kernel/futex.c was moved into kernel/futex/core.c in
preparation of the split-up of the implementation in various files.

Point kernel-doc references to the new files as otherwise the
documentation shows errors on build:

    [...]
    Error: Cannot open file ./kernel/futex.c
    Error: Cannot open file ./kernel/futex.c
    [...]
    WARNING: kernel-doc './scripts/kernel-doc -rst -enable-lineno -sphinx-version 3.4.3 -internal ./kernel/futex.c' failed with return code 2

There is no direct upstream commit for this change. It is made in
analogy to commit bc67f1c454fb ("docs: futex: Fix kernel-doc
references") applied as consequence of the restructuring of the futex
code.

Don't know what has happened to it though.  :(

Hi Randy,

On Fri, Apr 21, 2023 at 05:03:15PM -0700, Randy Dunlap wrote:

It was applied, as bc67f1c454fb ("docs: futex: Fix kernel-doc
references") in 5.16-rc1. But 5.10.y and 5.15.y picked up from the
refactoring only 77e52ae35463 ("futex: Move to kernel/futex/"). 

So this change is a specific backport of subset of it, to 5.10.y and
5.15.y thus the commit message:

Here pointing out explicitly that there is no (direct) upstream commit
for it. 

Hope this helps,

Regards,
Salvatore

This is not the correct way to submit patches for inclusion in the
stable kernel tree.  Please read:
    https://www.kernel.org/doc/html/latest/process/stable-kernel-rules.html
for how to do this properly.

Oops, nope, this was sent just fine, my bot got it wrong, sorry for the
noise...
