[Qemu-devel] [PATCH for-2.11] iotests: Fix 176 on 32-bit host

2017-11-17 Thread Eric Blake
The contents of a qcow2 bitmap are rounded up to a size that matches the number of bits available for the granularity, but that granularity differs for 32-bit hosts (our default 64k cluster allows for 2M bitmap coverage per 'long') and 64-bit hosts (4M bitmap per 'long'). If the image is a multipl
