[PATCH v6 0/5] block: enhance handling of size-related BlockConf properties

[Roman Kagan <rvkagan@xxxxxxxxxxxxxx>]

BlockConf includes several properties counted in bytes.

Enhance their handling in a some aspects, specifically

- accept common size suffixes (k, m)
- perform consistency checks on the values
- lift the upper limit on physical_block_size and logical_block_size

Also fix the accessor for opt_io_size in virtio-blk to make it consistent with
the size of the field.

History:
v5 -> v6:
- fix forgotten xen-block and swim
- add prop_size32 instead of going with 64bit

v4 -> v5:
- re-split the patches [Philippe]
- fix/reword error messages [Philippe, Kevin]
- do early return on failed consistency check [Philippe]
- use QEMU_IS_ALIGNED instead of open coding [Philippe]
- make all BlockConf size props support suffixes
- expand the log for virtio-blk opt_io_size [Michael]

v3 -> v4:
- add patch to fix opt_io_size width in virtio-blk
- add patch to perform consistency checks [Kevin]
- check min_io_size against truncation [Kevin]

v2 -> v3:
- mention qcow2 cluster size limit in the log and comment [Eric]

v1 -> v2:
- cap the property at 2 MiB [Eric]
- accept size suffixes

Roman Kagan (5):
  virtio-blk: store opt_io_size with correct size
  block: consolidate blocksize properties consistency checks
  qdev-properties: blocksize: use same limits in code and description
  block: make size-related BlockConf properties accept size suffixes
  block: lift blocksize property limit to 2 MiB
