[Qemu-devel] [PATCH v8 02/15] block: Make bdrv_states public |
Date: |
Mon, 26 Oct 2015 21:39:06 +0100 |
When inserting a BDS tree into a BB, we will need to add the root BDS to
this list. Since we will want to do that in the blockdev-insert-medium
implementation in blockdev.c, we will need access to it there.
This patch is not exactly elegant, but bdrv_states will be removed in
the future anyway because we no longer need it since we have BBs.
