Subject: [PATCH 2/2] block-backend: process zoned requests in the current AioContext
Date: Tue, 15 Aug 2023 12:05:21 -0400 [thread overview]
Message-ID: <20230815160521.3357063-3-stefanha@redhat.com> (raw)
In-Reply-To: <20230815160521.3357063-1-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.
