Review of attachment 365148 [details] [review]:

The commit message could be more descriptive: how is the documentation being improved? I suggest something like: “gbytes: Clarify nullability for g_bytes_unref() in docs”

::: glib/gbytes.c
@@ +296,3 @@
  * Releases a reference on @bytes.  This may result in the bytes being
+ * freed. If bytes is NULL it simply returns, so there is no need to check
+ * against NULL before calling this function.

There’s no need to make the same point twice here. You could simplify the addition to “If @bytes is %NULL, it will return immediately.”.

gbytes: Clarify nullability for g_bytes_unref () in docs

Thanks. I tweaked the patch slightly before pushing, to add some missing gtk-doc syntax which got lost between my suggestion and the uploaded patch.
