Turn them all into uint32_t and use size-suffix-capable setters/getters on them; introduce DEFINE_PROP_SIZE32 and adjust DEFINE_PROP_BLOCKSIZE for that. (Making them uint64_t and reusing DEFINE_PROP_SIZE isn't justified because guests expect at most 32bit values.) Also, since min_io_size is exposed to the guest by scsi and virtio-blk devices as an uint16_t in units of logical blocks, introduce an additional check in blkconf_blocksizes to prevent its silent truncation. Signed-off-by: Roman Kagan --- v5 -> v6: - add prop_size32 instead of going with 64bit v4 -> v5: - make all BlockConf size props support suffixes - move qdev_prop_blocksize after qdev_prop_size, to reuse get_size -
