From 1e8c3525f3c5246722e0780a03bd844800d90813 Mon Sep 17 00:00:00 2001 From: Michal Privoznik Date: Wed, 11 May 2022 13:31:47 +0200 Subject: [PATCH] include: Introduce typed params for virDomainSetIOThreadParams wrt pool size Our public API offers virDomainSetIOThreadParams() function which allows users to set various aspects of IOThreads. Introduce two new typed parameters: VIR_DOMAIN_IOTHREAD_THREAD_POOL_MIN and VIR_DOMAIN_IOTHREAD_THREAD_POOL_MAX which will allow users to modify the thread-pool-min and thread-pool-max attributes of an iothread.
