-Subject: [PATCH] migration/block-dirty-bitmap: fix loading bitmap when there
- is an iothread
-
-The bdrv_create_dirty_bitmap() function (which is also called by
-bdrv_dirty_bitmap_create_successor()) uses bdrv_getlength(bs). This is
-a wrapper around a coroutine, and thus uses bdrv_poll_co(). Polling
-tries to release the AioContext which will trigger an assert() if it
-hasn't been acquired before.
-
-The issue does not happen for migration, because there we are in a
-coroutine already, so the wrapper will just call bdrv_co_getlength()
-directly without polling.
