  "message": "block: Add blk_new_open()\n\nblk_new_with_bs() creates a BlockBackend with an empty BlockDriverState\nattached to it. Empty BDSs are not nice, therefore add an alternative\nfunction which combines blk_new_with_bs() with bdrv_open().\n\nNote: In contrast to bdrv_open() which takes a BlockDriver parameter,\nblk_new_open() does not take such a parameter. This is because\nbdrv_open() opens a BlockDriverState, therefore it is natural to be able\nto set the BlockDriver for that BDS. The fact that bdrv_open() can open\nmore than a single BDS is merely some form of a byproduct.\n\nblk_new_open() on the other hand is intended to be used to create a\nwhole tree of BlockDriverStates. Therefore, setting a single BlockDriver\ndoes not make much sense. Instead, the drivers to be used for each of\nthe nodes must be configured through the \"options\" QDict; including the\ndriver of the root BDS.\n\nSigned-off-by: Max Reitz \u003cmreitz@redhat.com\u003e\nReviewed-by: Eric Blake \u003ceblake@redhat.com\u003e\nReviewed-by: Kevin Wolf \u003ckwolf@redhat.com\u003e\nMessage-id: 1423162705-32065-3-git-send-email-mreitz@redhat.com\nSigned-off-by: Stefan Hajnoczi \u003cstefanha@redhat.com\u003e\n",
