[Qemu-devel] [PATCH v14 15/20] file-posix: Add 'locking' option

[Fam Zheng <famz@redhat.com>]

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.
