Hi all, Add a short functional test for the new GETFSREFCOUNTS ioctl that allows userspace to query reference count information for a given range of physical blocks.

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=report-refcounts xfsprogs git tree: https://git.kernel.org/cgit/linux/kernel/git/djwong/xfsprogs-dev.git/log/?h=report-refcounts fstests git tree: https://git.kernel.org/cgit/linux/kernel/git/djwong/xfstests-dev.git/log/?h=report-refcounts --- common/rc | 4 + doc/group-names.txt | 1 tests/xfs/122.out | 2 + tests/xfs/1921 | 168 +++++++++++++++++++++++++++++++++++++++++++++++++++ tests/xfs/1921.out | 4 + 5 files changed, 177 insertions(+), 2 deletions(-) create mode 100755 tests/xfs/1921 create mode 100644 tests/xfs/1921.out
