Please improve such a change description with imperative wordings.
https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/tree/Documentation/process/submitting-patches.rst?h=v6.10-rc3#n94

Can an adjusted summary phrase become also a bit more helpful?

Would you become interested to apply a statement like “guard(mutex)(&priv->mbox.lock);”?

Can unique include guards be more desirable also for this software?
