From b9b10c35e5c8bdb800601b142c44a4bd2da5a6d2 Mon Sep 17 00:00:00 2001 From: Kevin Wolf Date: Fri, 3 Feb 2023 16:21:50 +0100 Subject: block: Mark public read/write functions GRAPH_RDLOCK This adds GRAPH_RDLOCK annotations to declare that callers of bdrv_co_pread*/pwrite*() need to hold a reader lock for the graph. For some places, we know that they will hold the lock, but we don't have the GRAPH_RDLOCK annotations yet. In this case, add assume_graph_lock() with a FIXME comment. These places will be removed once everything is properly annotated.
