[PATCH 21/21] block: Mark bdrv_add/del_child() and caller GRAPH_WRLOCK

The functions read the parents list in the generic block layer, so we need to hold the graph lock already there. The BlockDriver implementations actually modify the graph, so it has to be a writer lock. Signed-off-by: Kevin Wolf --- include/block/block-global-state.h | 8 +---
