    Subject[PATCH 5.17 313/772] perf tools: Add missing headers needed by util/data.h
    Date
    From: Yang Jihong <yangjihong1@huawei.com>

    [ 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.

    Fixes: 258031c017c353e8 ("perf header: Add DIR_FORMAT feature to describe directory data")
