Hi all, Here is a general regression test to make sure that we can invoke the xfs_repair feature to add new features to V5 filesystems without errors. There are already targeted functionality tests for inobtcount and bigtime; this new one exists as a general upgrade exerciser. If you're going to start using this code, I strongly recommend pulling from my git trees, which are linked below. This has been running on the djcloud for months with no problems. Enjoy! Comments and questions are, as always, welcome. --D xfsprogs git tree: https://git.kernel.org/cgit/linux/kernel/git/djwong/xfsprogs-dev.git/log/?h=upgrade-older-features fstests git tree: https://git.kernel.org/cgit/linux/kernel/git/djwong/xfstests-dev.git/log/?h=upgrade-older-features --- tests/xfs/1856 | 247 ++++++++++++++++++++++++++++++++++++++++++++++++++++ tests/xfs/1856.out | 2 2 files changed, 249 insertions(+) create mode 100755 tests/xfs/1856 create mode 100644 tests/xfs/1856.out
