Miklos, This series is complementary to the whiteouts expose patches. Patch 2 restores origin xattr on lookup of merge dir (that was copied up before v4.12). Patch 3 sets a 'null' origin fh on dir if we happen to iterate an 'impure' dir and find a whiteout while looking for copy ups. This is expected to happen if merge dir was copied up before v4.12, but files inside it were copied up after v4.12. This series is currently based on top of non-samefs series and all patches for v4.15 are piled on my overlayfs-devel branch [1]. Let me know if you want me to rebase them differently. I enhanced Zhangyi's xfstest overlay/031, which tests for exposed whiteouts to cover the 2 cases addressed by this series. The enhanced test is available on my xfstests branch [2]. Zhangyi, I would appreciate a review of those patches and the test changes. Thanks, Amir.
