From 0f86afde66ea0d9a383878223ac07bd111c69692 Mon Sep 17 00:00:00 2001 From: Stefan Hajnoczi Date: Tue, 12 Sep 2023 19:10:36 -0400 Subject: [PATCH] block-backend: process zoned requests in the current AioContext Process zoned requests in the current thread's AioContext instead of in the BlockBackend's AioContext. There is no need to use the BlockBackend's AioContext thanks to CoMutex bs->wps->colock, which protects zone metadata.
