And thanks for providing a link to the rationale. But the URL contains "latest", so I think it may break if deprecated.rst or the section is ever renamed. I think I would prefer if we could reference the current text, e.g., via https://www.kernel.org/doc/html/v5.7-rc7/process/deprecated.html#implicit-switch-case-fall-through (The v5.7 doc would be better but doesn't seem to be generated yet; I pinged the helpdesk about that.) Or we could refer to b9918bdcac1f ("Documentation/process: Add fallthrough pseudo-keyword"), although it's not nearly as pretty as the HTML. > Signed-off-by: Gustavo A. R.

Replace the existing /* fall through */ comments and its variants with the new pseudo-keyword macro fallthrough[1]. Also, remove unnecessary fall-through markings when it is the case.
