Subject: [PATCH v2] wil6210: Replace %pK with %p
Date: Fri, 18 Sep 2026 22:11:45 +0200 [thread overview]
Message-ID: <20260918201145.kQDy1UrD@linutronix.de> (raw)
In-Reply-To: <35e7ac7d-534a-4001-b076-56ca3e12bdb3@oss.qualcomm.com>
Commit 71338aa7d050c ("net: convert %p usage to %pK") which is from
2011 and changed the %p annotation for pointer to %pK. Back then the
default behaviour for %p was to print the pointer. The %pK modifier was
introduced to able to control the behaviour of specific pointer values
without changing the behaviour of %p for everyone. It was dedicated to
avoid leaking pointers via /proc.
Things changed over time. The default behaviour for %p is now to print a
hash pointer which does not leak the address but allows to correlate if
two pointers are equal. I intend to remove %pK from the library.
Replace %pK with %pK in order to retain the pointer output for
debugging.
