[Qemu-devel] [PATCH RFC 0/3] block: Backdoor to skip image locking in qemu-io/qemu-img
Tue, 14 Mar 2017 10:39:30 +0800
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
