qemu_coroutine_create associates @co to qemu_aio_context but we poll blk's context below. If the coroutine yields, it may never get resumed again. Use bdrv_coroutine_enter to make sure we are starting the I/O on the right context. Signed-off-by: Fam Zheng <famz@redhat.com> --- qemu-io-cmds.c | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-)
