[Qemu-devel] [PATCH 0/2] block: fix backing file overriding

[Fam Zheng]

The backing.file.filename option is not working as expected: if there's also a
backing file name from the format driver, adding this option fails bdrv_open;
if there's no backing file name info in the image, "info block" doesn't show
the overrided file name.

A test case is updated to catch these issues.
