New test case to test if the minimal device size given by "mkfs.btrfs" failure case is valid. Signed-off-by: Qu Wenruo <quwenruo.btrfs@gmx.com> --- changelog: v2: Remove tailing whitespace. Use more accurate regex to match minimal device size, suggested by Lu Fengqi. --- tests/common | 57 +++++++++++++++++++++++++++++++- tests/mkfs-tests/010-small-image/test.sh | 51 ++++++++++++++++++++++++++++ 2 files changed, 107 insertions(+), 1 deletion(-) create mode 100755 tests/mkfs-tests/010-small-image/test.sh
