fts: enable leaf optimization for XFS XFS provides usable dirent.d_type only for DT_DIR, but the noleaf optimization still applies, as confirmed with: test $(($(find . -maxdepth 1 -type d | wc -l) + 1)) = $(stat -c %h .) Enabling this gives significant traversal speedup. Testing with find(1) gives: $ time find/find-before /usr/share >/dev/null real 0m0.410s user 0m0.145s sys 0m0.266s $ time find/find-after /usr/share >/dev/null real 0m0.278s user 0m0.147s sys 0m0.131s * lib/fts.c (leaf_optimization_applies): Add XFS to the white list.
