From a9515df4d66da34cbc2938e4c1f46015fc74ff93 Mon Sep 17 00:00:00 2001 From: Stefano Garzarella Date: Tue, 5 Oct 2021 18:11:57 +0200 Subject: [PATCH] block/aio_task: assert `max_busy_tasks` is greater than 0 All code in block/aio_task.c expects `max_busy_tasks` to always be greater than 0. Assert this condition during the AioTaskPool creation where `max_busy_tasks` is set.
