tools/include: Sync filesystem headers with the kernel sources
To pick up changes from: 0f9ca80fa4f9 fs: Add initial atomic write support info to statx f9af549d1fd3 fs: export mount options via statmount() 0a3deb11858a fs: Allow listmount() in foreign mount namespace 09b31295f833 fs: export the mount ns id via statmount d04bccd8c19d listmount: allow listing in reverse order bfc69fd05ef9 fs/procfs: add build ID fetching to PROCMAP_QUERY API ed5d583a88a9 fs/procfs: implement efficient VMA querying API for /proc/<pid>/maps This should be used to beautify FS syscall arguments and it addresses these tools/perf build warnings: Warning: Kernel ABI header differences: diff -u tools/include/uapi/linux/stat.h include/uapi/linux/stat.h diff -u tools/perf/trace/beauty/include/uapi/linux/fs.h include/uapi/linux/fs.h diff -u tools/perf/trace/beauty/include/uapi/linux/mount.h include/uapi/linux/mount.h diff -u tools/perf/trace/beauty/include/uapi/linux/stat.h include/uapi/linux/stat.h Please see tools/include/uapi/README for details (it's in the first patch of this series).
