[PULL 12/14] block-backend: process zoned requests in the current AioContext |
Date: |

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.
