> Subject: [Intel-wired-lan] [PATCH net-next 6/7] ice: Don't use %pK through
> printk or tracepoints
>
> In the past %pK was preferable to %p as it would not leak raw pointer values
> into the kernel log.
> Since commit ad67b74d2469 ("printk: hash addresses printed with %p") the
> regular %p has been improved to avoid this issue.
> Furthermore, restricted pointers ("%pK") were never meant to be used
> through printk(). They can still unintentionally leak raw pointers or acquire
> sleeping looks in atomic contexts.
>
> Switch to the regular pointer formatting which is safer and easier to reason
> about.
> There are still a few users of %pK left, but these use it through seq_file,
> for
> which its usage is safe.
