Subject: Re: [PATCH V11 4/5] vsprintf: add printk specifier %px

Because people who introduce this stupid %p hashing can't be bothered
to actually audit users:

	static int show_timer(struct seq_file *m, void *v)
	        seq_printf(m, "signal: %d/%p\n",

Overall, this %px thing doesn't matter. Developers will quickly learn
than %p gives some useless irreversible values and start using %px
everywhere. Soon someone will use %px in the wrong place and new
non-standard format specifier will be added.
