Re: [PATCH for-9.1 v2 09/11] hostmem: add a new memory backend based on POSIX shm_open()

[David Hildenbrand]

+    mode = 0;
+    oflag = O_RDWR | O_CREAT | O_EXCL;
+    backend_name = host_memory_backend_get_name(backend);
+
+    /*
+     * Some operating systems allow creating anonymous POSIX shared memory
+     * objects (e.g. FreeBSD provides the SHM_ANON constant), but this is not
+     * defined by POSIX, so let's create a unique name.
+     *
+     * From Linux's shm_open(3) man-page:
+     *   For  portable  use,  a shared  memory  object should be identified
+     *   by a name of the form /somename;"
+     */
+    g_string_printf(shm_name, "/qemu-" FMT_pid "-shm-%s", getpid(),
+                    backend_name);

Hm, shouldn't we just let the user specify a name, and if no name was 
specified, generate one ourselves?

I'm also not quite sure if "host_memory_backend_get_name()" should be 
used for the purpose here.
