| # FS QA Test 011 |
| # |
| # test overlay private xattr on overlayfs with multiple lower dirs, all the |
| # lower layers except the lowest one should honor overlay private xattr |
| # "trusted.overlay", which means it should not be visible to user. |
| # |
| # Commit b581755b1c56 ("ovl: xattr filter fix") fixed this issue. |
