[Qemu-devel] [PATCH v6 37/42] block: Leave BDS.backing_file constant

2019-08-09 Thread Max Reitz
Parts of the block layer treat BDS.backing_file as if it were whatever the image header says (i.e., if it is a relative path, it is relative to the overlay), other parts treat it like a cache for bs->backing->bs->filename (relative paths are relative to the CWD). Considering
