[Qemu-devel] [PATCH v2 9/9] tests: Add coverage for recent block geometry fixes

2016-11-17 Thread Eric Blake
Use blkdebug's new geometry constraints to emulate setups that have caused recent regression fixes: write zeroes asserting when running through a loopback block device with max-transfer smaller than cluster size, and discard rounding away requests that were not aligned to power-of-two boundaries.
