From 3574499a1e5e420c3e72d0e283cfb2b13bce672e Mon Sep 17 00:00:00 2001 From: Kevin Wolf Date: Fri, 29 Sep 2023 16:51:54 +0200 Subject: block: Mark bdrv_get_specific_info() and callers GRAPH_RDLOCK This adds GRAPH_RDLOCK annotations to declare that callers of bdrv_get_specific_info() need to hold a reader lock for the graph. This removes an assume_graph_lock() call in vmdk's implementation.
