This adds a test for having multiple BlockBackends in one BDS tree. In
this case, there is one BB for the protocol BDS and one BB for the
format BDS in a simple two-BDS tree (with the protocol BDS and BB added
first).
When bdrv_close_all() is executed, no cached data from any BDS should be
lost;
Currently, bdrv_close_all() force-closes all BDSs with a BlockBackend,
which can lead to data corruption (see the iotest added in the final
patch of this series) and is most certainly very ugly.
This series reworks bdrv_close_all() to instead eject the BDS trees from
all BlockBackends and then
The only remaining user of the BDS close notifiers is NBD which uses
them to determine when a BDS tree is being ejected. This patch removes
the BDS-level close notifiers and adds a notifier list to the
BlockBackend structure that is invoked whenever a BDS is removed.
Symmetrically to that,
