Hi all, These are the test adjustments that are required for parent pointers. There's also a few new tests to ensure that the GETPARENTS ioctl (and file extent can cross an rtgroup boundary. The best advantage for rtgroups will become evident later when we get to adding rmap and reflink to the realtime volume, since the geometry constraints are the same for rt groups and AGs. Hence we can reuse all that code directly. 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 kernel git tree: https://git.kernel.org/cgit/linux/kernel/git/djwong/xfs-linux.git/log/?h=pptrs xfsprogs git tree: https://git.kernel.org/cgit/linux/kernel/git/djwong/xfsprogs-dev.git/log/?h=pptrs fstests git tree: https://git.kernel.org/cgit/linux/kernel/git/djwong/xfstests-dev.git/log/?h=pptrs xfsdocs git tree: https://git.kernel.org/cgit/linux/kernel/git/djwong/xfs-documentation.git/log/?h=pptrs --- common/parent | 209 +++++++++ common/populate | 38 ++ common/rc | 7 common/xfs | 27 + doc/group-names.txt | 1 src/popdir.pl | 11 tests/generic/1834 | 93 ++++ tests/generic/1834.out | 2 tests/xfs/018 | 4 tests/xfs/021 | 15 + tests/xfs/021.cfg | 1 tests/xfs/021.out.default | 0 tests/xfs/021.out.parent | 62 +++ tests/xfs/122.out | 3 tests/xfs/1851 | 116 +++++ tests/xfs/1851.out | 69 +++ tests/xfs/1852 | 69 +++ tests/xfs/1852.out | 1002 +++++++++++++++++++++++++++++++++++++++++++++ tests/xfs/1853 | 85 ++++ tests/xfs/1853.out | 14 + tests/xfs/191 | 3 tests/xfs/206 | 3 tests/xfs/288 | 4 tests/xfs/306 | 9 24 files changed, 1839 insertions(+), 8 deletions(-) create mode 100644 common/parent create mode 100755 tests/generic/1834 create mode 100644 tests/generic/1834.out create mode 100644 tests/xfs/021.cfg rename tests/xfs/{021.out => 021.out.default} (100%) create mode 100644 tests/xfs/021.out.parent create mode 100755 tests/xfs/1851 create mode 100644 tests/xfs/1851.out create mode 100755 tests/xfs/1852 create mode 100644 tests/xfs/1852.out create mode 100755 tests/xfs/1853 create mode 100644 tests/xfs/1853.out
