From: Yang Jihong <yangjihong1@huawei.com> stable inclusion from stable-v5.10.121 commit d5773db56ce963fd1aae62ea74a4e0a49effb595 category: bugfix bugzilla: https://gitee.com/openeuler/kernel/issues/I5L6CQ Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id=... -------------------------------- [ Upstream commit 4d27cf1d9de5becfa4d1efb2ea54dba1b9fc962a ] 'struct perf_data' in util/data.h uses the "u64" data type, which is defined in "linux/types.h". If we only include util/data.h, the following compilation error occurs: util/data.h:38:3: error: unknown type name ‘u64’ u64 version; ^~~ Solution: include "linux/types.h." to add the needed type definitions.
