See patch 4 for the description of the bug fixed. v3: - Don't allow blocking the monitor for a zero write in block_resize (even though we can already blockfor other reasons there). This is mainly responsible for the increased complexity compared to v2. Personally, I think this is not an improvement over v2, but if this is what it takes to fix a corruption issue in 4.2... [Max] - Don't use huge image files in the test case [Vladimir]
v2: - Switched order of bs->total_sectors update and zero write [Vladimir] - Fixed coding style [Vladimir] - Changed the commit message to contain what was in the cover letter - Test all preallocation modes - Test allocation status with qemu-io 'map' [Vladimir] Kevin Wolf (8): block: bdrv_co_do_pwrite_zeroes: 64 bit 'bytes' parameter block: Add no_fallback parameter to bdrv_co_truncate() qcow2: Declare BDRV_REQ_NO_FALLBACK supported block: truncate: Don't make backing file data visible iotests: Add qemu_io_log() iotests: Fix timeout in run_job() iotests: Support job-complete in run_job() iotests: Test committing to short backing file include/block/block.h | 5 +- include/sysemu/block-backend.h | 2 +- block/block-backend.c | 4 +- block/commit.c | 4 +- block/crypto.c | 4 +- block/io.c | 55 +++++++-- block/mirror.c | 2 +- block/parallels.c | 6 +- block/qcow.c | 4 +- block/qcow2-refcount.c | 2 +- block/qcow2.c | 22 ++-- block/qed.c | 2 +- block/raw-format.c | 2 +- block/vdi.c | 2 +- block/vhdx-log.c | 2 +- block/vhdx.c | 6 +- block/vmdk.c | 10 +- block/vpc.c | 2 +- blockdev.c | 2 +- qemu-img.c | 2 +- qemu-io-cmds.c | 2 +- tests/test-block-iothread.c | 6 +- tests/qemu-iotests/274 | 152 ++++++++++++++++++++++++ tests/qemu-iotests/274.out | 203 +++++++++++++++++++++++++++++++++ tests/qemu-iotests/group | 1 + tests/qemu-iotests/iotests.py | 11 +- 26 files changed, 463 insertions(+), 52 deletions(-) create mode 100755 tests/qemu-iotests/274 create mode 100644 tests/qemu-iotests/274.out -- 2.20.1
