Bigger notable changes:
* Commit 1a30b0f5d7 ("block: .bdrv_open is non-coroutine and
unlocked") broke the PVE backup patches, in particular setting up
the backup dump block driver, because bdrv_new_open_driver() cannot
be called from a coroutine. To fix it, bdrv_co_open() is used
instead, and while it's a much more involved function, the result
should be essentially the same. The only difference I noticed is
that the BDRV_O_ALLOW_RDWR flag is also set in the resulting bds
(block driver state), but that shouldn't hurt.
Smaller notable changes:
* aio_set_fd_handler() dropped its 'is_external' parameter stating
that all callers now pass false in 60f782b6b7 ("aio: remove
aio_disable_external() API"). The calls in the PVE patches also
passed false, so just drop the parameter too.
* global_state_store() does not have a return value anymore, so the
user in the PVE savevm-async patch was adapted. For context, see
c33f1829f8 ("migration: never fail in global_state_store()").
* Renames affecting the PVE savevm-async patch:
migrate_use_block() -> migrate_block() and ram_counters -> mig_stats
9d4b1e5f22 ("migration: Move migrate_use_block() to options.c")
aff3f6606d ("migration: Rename ram_counters to mig_stats")

Subject: [PATCH] migration/block-dirty-bitmap: migrate other bitmaps even if
|
|
one fails
|
|
|
|
If the checks in bdrv_dirty_bitmap_check fail, that only means that this
|
|
one specific bitmap cannot be migrated. That is not an error condition
|
|
for any other bitmaps on the same block device.
|
|
|
|
Fixes dirty-bitmap migration with sync=bitmap, as the bitmaps used for
|
|
that are obviously marked as "busy", which would cause none at all to be
|
|
transferred.
