[Qemu-devel] [RFC PATCH 0/3] block: add support for 4k logical blocks

[Paolo Bonzini]

This series adds support for 4k logical blocks by bouncing requests
unless the host's logical_block_size is also 4096.

Paolo Bonzini (3):
  block: add bdrv_get_alignment, use it
  raw: implement raw_get_alignment
  block: do not rely on the buffer alignment passed to the guest
