[Qemu-block] [PATCH v16 15/22] file-posix: Add 'locking' option |
Date: |
Tue, 2 May 2017 16:18:25 +0800 |
Making this option available even before implementing it will let
converting tests easier: in coming patches they can specify the option
already when necessary, before we actually write code to lock the
images.
