At least in drm we have a lot of such comments (as non-kerneldoc) right above struct members to explain some details. Common examples are: - locks, with a description of what they protect and maybe also how they nest. - vfunc ops structs, with a per-function description of what each hook does. - tricky stuff which can't be described in one sentence only. So it's not just huge structs by number of members, but huge by number of comment lines. Trying to stuff that all into the top kerneldoc comment means that it's much harder to jump to the right comment, and it's also easier to ignore the comments (since it e.g. won't show up in the diff context). The current approach at least in drm is to duplicate comments and that just results in inconsistency. > I'm wondering if we need a kernel summit session on commenting > conventions, markdown-in-kerneldoc, etc?

The only comment I've seen is to maybe use gtkdoc, but that would be a pain since it's slightly incompatible with kerneldoc. And it's the improved tooling I really need for my long-term plan to get solid docs for drm & drm/i915. Next step is to start building a proper doc writer team to make all the bits we already have into a consistent hole (and nag developers to fill in the areas still undocumented). For that I've already pulled Danilo's patches into the drm-intel integration tree and I plan to use them for any further drm kerneldoc I write since we really need them.
