-Subject: [PATCH] block: Fix AioContext locking in qmp_block_resize()
-
-The AioContext must be unlocked before calling blk_co_unref(), because
-it takes the AioContext lock internally in blk_unref_bh(), which is
-scheduled in the main thread. If we don't unlock, the AioContext is
-locked twice and nested event loops such as in bdrv_graph_wrlock() will
-deadlock.
