[1] The original test was a bit naiive, not taking into account renames, drop caches and mount cycle. All those are added by this series. Since the original test does not pass on stable kernel nor will it pass with the changes by this series, these changes should cause no regressions to testers. My work covers only the inode numbers returned from stat(2) and not the inode numbers returned in d_ino from readdir(3), so the 'find -inum' part of this test could still fail with my overlayfs patches. However, I ran my tests in kvm-xfstests VM, where 'find -inum' called stat(2) for each entry, so the test did pass. I will dig deeper into this behavior when I work on fixing d_ino values in the next part of my work. Changes since v1: - Re-factor check_inode_numbers - Move -maxdepth option position - Fix somme comments - Blurb more in commit messages Amir.
