+Subject: [PATCH] module: Don't complain when a module is absent
+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+The current implementation depends on a configure-time generated list of
+block modules. When any of them is absent, module_load() emits a warning.
+
+This is suboptimal because extracting code to modules was mainly done to
+allow separate packaging of modules with intrusive dependencies. Absence
+of optional packages then leads to absence of modules and an error
+message, which users may recognize as new and report as error.
