Follow-up Comment #2, patch #5316 (project grep):
Many parts of coreutils assume st_dev/st_ino are reliable, e.g., SAME_INODE.
With multiple mounts (e.g., NFS) it's possible for the same file to have
different st_dev values.
GNU tar, on occasion, also looks at st_birthtime, which is a win on systems
that support it, as st_birthtime disambiguates the case when inode numbers are
reused. gnulib/fts/coreutils should probably use st_birthtime too, if
available.
