From 82618d7bc341cb93b9ce9c206d7ec84cebe83d00 Mon Sep 17 00:00:00 2001 From: Emanuele Giuseppe Esposito Date: Fri, 13 Jan 2023 21:42:07 +0100 Subject: block: Convert bdrv_get_allocated_file_size() to co_wrapper bdrv_get_allocated_file_size() is categorized as an I/O function, and it currently doesn't run in a coroutine. We should let it take a graph rdlock since it traverses the block nodes graph, which however is only possible in a coroutine. Therefore turn it into a co_wrapper to move the actual function into a coroutine where the lock can be taken.
