+Subject: [PATCH] formatter: reserve_minimum in end_ methods
+
+In highly nested json objects it's possible to have a lot of consecutive
+closing characters that are added by end_array and end_object. These
+methods adds one byte without checking the buffer capacity, so it's
+possible to try to write when there's no capacity.
+
+This patch makes sure that the buffer has at least minimum space before
+writing.
+
+This is the upstream commit that removes this check: c369ea44820e2e0798f17f99a0dff65bec2186a9
+```
