Surprise! "du -x non-DIR" would print nothing. Note that the problem arises only when processing a non-directory specified on the command line. Not surprisingly, "du -x" still works as expected for any directory argument. When performing its same-file-system check, du may skip an entry only if it is at fts_level 1 or greater. Command-line arguments are at fts_level == 0 (FTS_ROOTLEVEL). * src/du.c (process_file): Don't use the top-level FTS->fts_dev when testing for --one-file-system (-x). It happens to be valid for directories, but it is always 0 for a non-directory. * tests/du/one-file-system: Add tests for this. * NEWS (Bug fixes): Mention it. Reported by Daniel Stavrovski in http://bugs.gnu.org/10967. Introduced by commit v8.14-95-gcfe1040.
