Re: [PATCH] cifs: Convert to use the fallthrough macro

[Steve French]

Is this conversion from "/* Fallthrough */"   to the preferred (?)
"fallthrough;" documented anywhere?

All I see is a few fs changesets like:

commit c730ae0c6bb3125ccb776fb2ab6abbdff500c02c
Author: Marcos Paulo de Souza <mpdesouza@xxxxxxxx>

    btrfs: convert comments to fallthrough annotations

    Convert fall through comments to the pseudo-keyword which is now the
    preferred way.

And the vast majority of places (33 vs. 4) use "/* Fallthrough */ in
the fs directory
