Miklos, This version provides a solution for some interesting non-samefs cases: - All the ext* family - Many other fs with default encode_fh - xfs that is not huge with overlay 'xino' mount option - tmpfs that is not on a machine with jurassic uptime with 'xino' I tested this with Chandan's upstream overlay/041 xfstest for consistent d_ino in non-samefs setup. Results are: - Test passes for ext4 - Test fails for xfs - Test fails for xfs with OVERLAY_MOUNT_OPTIONS=-oxino, but this is because of a test bug - With the test bug fix available at [2] test passes with xfs and OVERLAY_MOUNT_OPTIONS=-oxino All the exportfs tests also pass with these changes and either ext4 or xfs with OVERLAY_MOUNT_OPTIONS=-oxino. Changes since v7: - Drop patches for building impure cache for non-samefs subdirs - Dropped patch "update cache version of impure parent on rename" because it is not relevant to this series - Remap lower inode numbers for 32bit inode file systems - Add mount option 'xino' for opting-in to use high inode bits Thanks, Amir.
