Subject: Re: [PATCH v6 5/8] tracing: add new type "%pd/%pD" in readme_msg[]

Hi Ye,

Can you split this into 

(1)
> -	"\t           symstr, <type>\\[<array-size>\\]\n"
> +	"\t           symstr, %pd, <type>\\[<array-size>\\]\n"

and 

(2)
> -	"\t           symstr, %pd, <type>\\[<array-size>\\]\n"
> +	"\t           symstr, %pd/%pD, <type>\\[<array-size>\\]\n"

And merge (1) into [PATCH 3/8], (2) into [PATCH 5/8], so that
the feature patch itself updates the readme text?

This is because even if one of the patch drops, others can
show its feature on readme.

Thank you,
