[PATCH] bcache: fix kernel-doc warning on CLOSURE_CALLBACK

[PATCH] bcache: fix kernel-doc warning on CLOSURE_CALLBACK

[Rosen Penev]

bch_data_insert() is defined through the CLOSURE_CALLBACK() macro, which
kernel-doc cannot see through, so the kernel-doc comment above it
produces:

  request.c:308 function parameter 'bch_data_insert' not described in 'CLOSURE_CALLBACK'
  request.c:308 expecting prototype for bch_data_insert(). Prototype was for CLOSURE_CALLBACK() instead

Turn it into a regular block comment, and drop the @cl line along
with the kernel-doc markup.

The patch is fine to me. Can you provide the detailed LLM name here?

It was Opencode's Big Pickle IIRC. Current documentation says to just say LLM.

Documentation file coding-assistants.rst suggests,

 43 Attribution
 44 ===========
 45
 46 When AI tools contribute to kernel development, proper attribution
 47 helps track the evolving role of AI in the development process.
 48 Contributions should include an Assisted-by tag in the following format::
 49
 50   Assisted-by: LLM [TOOL1] [TOOL2]
 51
 52 * ``[TOOL1] [TOOL2]`` are optional specialized analysis tools used
 53   (e.g., coccinelle, sparse, smatch, clang-tidy)
 54
 55 Basic development tools (git, gcc, make, editors) should not be listed.
 56
 57 Example::
 58
 59   Assisted-by: LLM coccinelle sparse

Yes,  only listing LLM is the bottom line, and list the detailed model name is better.

If you don’t want to post v2 patch, you can give me a line of Assisted-by: , I can replace it in the patch.

Thanks.
