Subject: [PULL 12/14] block-backend: process zoned requests in the current AioContext
Date: Mon,  4 Sep 2023 16:36:41 +0200	[thread overview]
Message-ID: <20230904143643.259916-13-kwolf@redhat.com> (raw)
In-Reply-To: <20230904143643.259916-1-kwolf@redhat.com>

From: Stefan Hajnoczi <stefanha@redhat.com>

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.
