From 5529b02da2dcd1ef6bc6cd42d4fbfb537fe2276f Mon Sep 17 00:00:00 2001 From: Lukas Straub Date: Tue, 18 May 2021 13:42:14 +0200 Subject: block/quorum: Provide .bdrv_co_flush instead of .bdrv_co_flush_to_disk The quorum block driver uses a custom flush callback to handle the case when some children return io errors. In that case it still returns success if enough children are healthy. However, it provides it as the .bdrv_co_flush_to_disk callback, not as .bdrv_co_flush. This causes the block layer to do it's own generic flushing for the children instead, which doesn't handle errors properly. Fix this by providing .bdrv_co_flush instead of .bdrv_co_flush_to_disk so the block layer uses the custom flush callback.
