To pick the changes from:
825cf206ed ("statx: add direct I/O alignment information")
That add a constant that was manually added to tools/perf/trace/beauty/statx.c,
at some point this should move to the shell based automated way.
This silences this perf build warning:
Warning: Kernel ABI header at 'tools/include/uapi/linux/stat.h' differs from latest version at 'include/uapi/linux/stat.h'
