This patch series adds the functionality to change the backing file of existing
images. This includes simple renaming of a backing file without converting the
COW image as well as safe rebasing onto a different backing file that has some
changes compared to the current backing file.
v2:
- Added missing braces in copied code
v3:
- Added some missing error checks
- Fixed storing the backing file format in qcow2
- Open backing files with right format
v4:
- Handle bdrv_pwrite failure
Kevin Wolf (3):
block: Introduce BDRV_O_NO_BACKING
block: Add bdrv_change_backing_file
