[ 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: 258031c017 ("perf header: Add DIR_FORMAT feature to describe directory data")
