This is v9 of the image locking series. I redid the whole series, adopting the
"two locks" approach from Kevin and Max.
Depends on "[Qemu-devel] [PATCH] raw-posix: Rename 'raw_s' to 'rs'" in Max's
block branch.
Fam Zheng (14):
osdep: Add qemu_lock_fd and qemu_unlock_fd
block: Define BDRV_O_SHARE_RW
qemu-io: Set "share-rw" flag together with read-only
qemu-img: Set "share-rw" flag in read-only commands
block: Set "share-rw" flag in drive-backup when sync=none
block: Set "share-rw" flag for incoming migration
iotests: 055: Don't attach the drive to vm for drive-backup
iotests: 030: Read-only open image for getting map
iotests: 087: Don't attch test image twice
iotests: 085: Avoid image locking conflict
iotests: 091: Quit QEMU before checking image
tests: Use null-co:// instead of /dev/null as the dummy image
raw-posix: Implement image locking
tests: Add test-image-lock
