Eryu, Originally, I wrote overlay/049 to test online inconcsistency detection feature, which I wrote as a sub feature of NFS export, so the initial version of the test required and eanbled NFS export. Then, at some point, the test started to pass without NFS export enabled, which was a by-product of another fix for inotify I did around the same time. So the test got merged without requiring NFS export, but with said fix commit on next branch. On a recent discussion with Vivek, I realized that there was another "by-product" inconsistency detection introduced by the same fix commit and not covered by overlay/049. The variant overlay/059 checks for this case of malformed multiply referenced origin files. I wrote the test to support upcoming 'metacopy' feature by Vivek, so it requires and enables redirect_dir, which is harmless otherwise. I tested overlay/059 on several old kernels. The results are: - notrun on kernel < v4.10, before "redirect_dir" feature - pass on kernels < v4.12, before "origin" was introduced - fail on kernels < v4.16, before the fix commit - pass on newer kernels Amir Goldstein (2): overlay/049: update fix commit id overlay: test multiple origin references to the same lower file tests/overlay/049 | 4 +- tests/overlay/059 | 105 ++++++++++++++++++++++++++++++++++++++++++++++++++ tests/overlay/059.out | 2 + tests/overlay/group | 1 + 4 files changed, 110 insertions(+), 2 deletions(-) create mode 100755 tests/overlay/059 create mode 100644 tests/overlay/059.out -- 2.7.4 -- To unsubscribe from this list: send the line "unsubscribe linux-unionfs" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
