This series introduces a bottom intermediate node that eliminates the
dependency on the base that may change while stream job is running.
It happens when stream/commit parallel jobs are running on the same
backing chain. The base node of the stream job may be a top node of
the parallel commit job and can change before the stream job is
completed. We avoid that dependency by introducing the bottom node.
v5: [resend by Vladimir]
01: use comment wording in block/io.c suggested by Alberto
Now the whole series are reviewed-by Alberto and me.
v4:
trace_stream_start reverted to the base.
bdrv_is_allocated_above_inclusive() deleted and the new parameter
'bool include_base' was added to the bdrv_is_allocated_above().
Andrey Shinkevich (2):
block: include base when checking image chain for block allocation
block/stream: introduce a bottom node
Vladimir Sementsov-Ogievskiy (1):
block/stream: refactor stream_run: drop goto
