[Qemu-devel] [PATCH 1/2] block: Set backing_hd to NULL after deleting it

It is safer to set backing_hd to NULL after deleting it so that any use after deletion is obvious during development. Happy segfaulting! This patch should be applied after Kevin Wolf's "vmdk: Convert to bdrv_open" so that vmdk does not segfault on close. Signed-off-by: Stefan Hajnoczi --- bloc
