[Qemu-devel] [PATCH v2 0/3] block: enforce constraints on block size properties

[Stefan Hajnoczi <stefanha@linux.vnet.ibm.com>]

This series ensures we only accept valid block sizes.  Although in theory block
sizes can vary a lot, the storage protocols (ATA, SCSI) as well as the QEMU
block layer implementation impose constraints.  Valid QEMU block sizes today
must meet:

 * Power of 2
 * Multiple of 512 bytes
 * Fits into uint16_t

Nicolae Mogoreanu <mogo@google.com> found that QEMU allows invalid block sizes
to be specified and this can cause it to crash when I/O is performed.
