Hi Greg,
The 21 Landlock commits merged for 5.19-rc1 and tagged with Cc stable@
should indeed be backported up to 5.15 . The first commits are pure
cosmetic changes but they need to be backported to avoid backport
conflicts (for this series and future backports). They help maintain
this subsystem, including to backport future changes. The following
changes up to commit 8ba0005ff418 ("landlock: Fix same-layer rule
unions") are required to fix some edge case issues (i.e. syscall
argument ordering checks and same-layer rule unions). New tests are
added to check that everything work as expected for these backportable
changes, and to make it possible for more test environments to run. I
successfully tested the backport of all these commits to 5.15 . Please
backport them to all stable branches.
Here is the full list of the commits to backport (already marked with
Cc: stable@xxxxxxxxxxxxxxx):

The patch below was submitted to be applied to the 5.18-stable tree.
I fail to see how this patch meets the stable kernel rules as found at
Documentation/process/stable-kernel-rules.rst.
I could be totally wrong, and if so, please respond to
<stable@xxxxxxxxxxxxxxx> and let me know why this patch should be
applied. Otherwise, it is now dropped from my patch queues, never to be
seen again.
thanks,

Let's follow a consistent and documented coding style. Everything may
not be to our liking but it is better than tacit knowledge. Moreover,
this will help maintain style consistency between different developers.
