The commit message:
SUNRPC: Optimize list definition method

Integrate list definition and initialization into LIST_HEAD macro
Only describes what the change does, not why it's needed. The body
just restates the diff in English.

A commit message should justify the change. For this patch, there's
no justification. Moreover the word "Optimize" in the subject is
misleading - it implies a benefit that doesn't exist.

If this change were genuinely needed, the commit message should
explain something like:

- "...to match the pattern used elsewhere in this file" (if applicable)
- "...as a prerequisite for X"
- "...to fix Y"

For example, is this patch part of a kernel-wide audit driven by a
code safety concern?
