I'm trying to test all the floating point instructions only. They
tend to begin with the letter f. Is there a way to have risugen only
use instructions that begin with the letter F?
Or, rather, force the open of a backing image if one was specified
for creation. Using a similar -unsafe option as rebase, allow qemu-img
to ignore the backing file validation if possible.
It may not always be possible, as in the existing case of if a filesize
for the new image was not specified.

Since we are already in coroutine context during the body of
bdrv_co_get_block_status(), we can shave off a few layers of
wrappers when recursing to query the protocol when a format driver
returned BDRV_BLOCK_RAW.
Note that we are already using the correct recursion later on in
the same function,

Now that the block layer takes care to request a lot less permissions
for inactive nodes, the special-casing in file-posix isn't necessary any
more.

Format drivers for inactive nodes don't need write/resize permissions on
their bs->file and can share write/resize with another VM (in fact, this
is the whole point of keeping images inactive). Represent this fact in
the op blocker system, so that image locking does the right thing
without special-
With image locking, permissions affect other qemu processes as well. We
want to be sure that the destination can run, so let's drop permissions
on the source when migration completes.

Instead of manually calling blk_resume_after_migration() in migration
code after doing bdrv_invalidate_cache_all(), integrate the BlockBackend
activation with cache invalidation into a single function. This is
achieved with a new callback in BdrvChildRole that is called by
bdrv_invalidate_cache_all
The proper order for inactivating block nodes is that first the parents
get inactivated and then the children. If we do things in this order, we
can assert that we didn't accidentally leave a parent activated when one
of its child nodes is inactive.

Migration code activates all block driver nodes on the destination when
the migration completes. It does so by calling
bdrv_invalidate_cache_all() and blk_resume_after_migration(). There is
one code path for precopy and one for postcopy migration, resulting in
four function calls, which used to hav
Fam's image locking series introduced some special-casing in the file-posix
driver that avoids taking locks when the image is inactive. While this works,
it really isn't the job of the file-posix driver, but the core block layer
should consider that inactive nodes require a lot less permissions.

Dear James,
Thanks a lot for your review and comments. I am very sorry for the
