[Qemu-devel] [PATCH 4/4] block/gluster: add missing QLIST_HEAD_INITIALIZER()

[Stefan Hajnoczi <stefanha@redhat.com>]

The "qemu/queue.h" data structures provide static initializer macros.
The QLIST version just initializes to NULL so code happens to work when
the initializer is forgotten.  Other types like SLIST are not so
forgiving because they set fields to non-NULL values.

The initializer macro should always be used for consistency and so that
no errors are introduced when switching between list/queue variants.
