[Qemu-devel] [PATCH v4 2/3] block/stream: refactor stream_run: drop goto |
Date: |
Mon, 8 Apr 2019 21:22:20 +0300 |
From: Vladimir Sementsov-Ogievskiy <address@hidden>
The goto is unnecessary in the stream_run() since the common exit
code was removed in the commit eb23654dbe43b549ea2a9ebff9d8e:
"jobs: utilize job_exit shim".
