Hi All, The master branch on the unionmount-testsuite tree [1] has been updated. Changes in this update: - Support testing nested overlayfs configurations The following test arguments: ./run --ovov --xino --verify setup a non-samefs nested overlay with --xino and demonstrate the best effort nature of xino - upper inode numbers are in the xino domain and lower inode numbers overflow xino bits and fallback to lower layer pseudo st_dev and the lower overlay st_ino. This was used to develop the recently merged ovl-ino changes. Thanks, Amir.
