From 62248b22d01e96a4d669cde0d7005bd51ebf9e76 Mon Sep 17 00:00:00 2001 From: Natanael Copa Date: Thu, 28 Mar 2024 11:59:13 +0100 Subject: tools/resolve_btfids: fix build with musl libc Include the header that defines u32. This fixes build of 6.6.23 and 6.1.83 kernels for Alpine Linux, which uses musl libc. I assume that GNU libc indirecly pulls in linux/types.h.
