From e113362e4cdfdcfe1d497e569527f70a0021333a Mon Sep 17 00:00:00 2001 From: Kevin Wolf Date: Tue, 9 May 2023 15:41:33 +0200 Subject: [PATCH] iotests: Test resizing image attached to an iothread This tests that trying to resize an image with QMP block_resize doesn't hang or otherwise fail when the image is attached to a device running in an iothread. This is a regression test for the recent fix that changed qmp_block_resize, which is a coroutine based QMP handler, to avoid calling no_coroutine_fns directly.
