Subject: [PATCH 0/2] kprobes: Adjustments for __counted_by addition

Hi all,

This series addresses the issues that I brought up at [1]. The first
change is the actual functional fix and the second change is something I
noticed while auditing this code, which is related but tangential to the
actual fix, since the current code has a correct calculation.

This resolves the issue for me when testing both clang 19 and GCC 15
(tip of tree, which is the only version that has __counted_by support).
