001/6:[----] [--] 'qcow2: Prefer byte-based calls into bs->file'
002/6:[----] [--] 'qcow2: Document some maximum size constraints'
003/6:[----] [--] 'qcow2: Reduce REFT_OFFSET_MASK'
004/6:[----] [--] 'qcow2: Don't allow overflow during cluster allocation'
005/6:[down] 'iotests: Add new test 220 for max compressed cluster offset'
006/6:[----] [--] 'qcow2: Avoid memory over-allocation on compressed images'
