Hi Kevin,

This tries to capture your idea to add a explicit command option in qemu-io and
qemu-img for user to specify "expect inconsistent data when reading image".
It's stored as a BDRV_O_ flag internally, I don't know if there is a cleaner
way or not.

It's depended on by image locking series because several test cases need to be
updated to use this flag.


Fam Zheng (3):
  block: Introduce BDRV_O_UNSAFE_READ
  qemu-img: Add --unsafe-read option to subcommands
  qemu-io: Add --unsafe-read option
