From 414ba9bad84bec1236f9756f7732fb4cc5ee0b18 Mon Sep 17 00:00:00 2001 From: Alessio Biancalana Date: Sun, 3 May 2026 17:58:07 +0200 Subject: [PATCH] fix(bpf): add explicit casts for mm_struct CO-RE relabels LLVM 22 promoted -Wincompatible-pointer-types from a warning to an error, breaking the implicit conversion from `const struct mm_struct *` to the relabeled `mm_struct___pre62` / `___post62` CO-RE types in exitstat.bpf.c. Add explicit casts so the file builds on both pre- and post-LLVM 22 toolchains.
