Subject: [PATCH for-4.2? v3 0/8] block: Fix resize (extending) of short overlays
Date: Fri, 22 Nov 2019 17:05:03 +0100 [thread overview]
Message-ID: <20191122160511.8377-1-kwolf@redhat.com> (raw)
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
