Its filename was mm-vmalloc-use-%p-for-pointer-formatting.patch This patch was dropped because it was merged into the mm-stable branch of git://git.kernel.org/pub/scm/linux/kernel/git/akpm/mm ------------------------------------------------------ From: Sebastian Andrzej Siewior Subject: mm/vmalloc: use %p for pointer formatting Date: Fri, 18 Sep 2026 12:50:13 +0200 Commit 45ec16908e84e ("mm: use %pK for /proc/vmallocinfo") introduced the %pK in order not to leak kernel pointers. Since commit ad67b74d2469d ("printk: hash addresses printed with %p") pointers are hashed by default and the behaviour can be controlled by `hash_pointers' boot argument. The policy on %p is to not introduce new ones. Removing %pK makes it possible to remove its handling from the library. Looking at the output, having the pointer in the output makes it possible to distinguish the individual entries. Use %p instead %pK. /proc/vmallocinfo has mode 0400, so this change doesn't make kernel pointer information available to unprivileged userspace.
