This removes the need for the CommitMethod enum Changes since v1: - split up the implementation in three separate commits - removed accidentally left over includes from testing Vincent Vanlaer (5): block: get type of block allocation in commit_run block: move commit_run loop to separate function block: refactor error handling of commit_iteration block: allow commit to unmap zero blocks block: add test non-active commit with zeroed data block/commit.c | 108 +++++++++++++++++++++++++------------ tests/qemu-iotests/315 | 95 ++++++++++++++++++++++++++++++++ tests/qemu-iotests/315.out | 54 +++++++++++++++++++ 3 files changed, 223 insertions(+), 34 deletions(-) create mode 100755 tests/qemu-iotests/315 create mode 100644 tests/qemu-iotests/315.out -- 2.44.1
