+Subject: [PATCH] api.c: preserve dirty flag when copying controller values
+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+When setting cgroup parameters with cgset fails, no error is reported.
+This is caused by the fact that cgroup_copy_controller_values is not
+preserving dirty flags of the values, so it's making all errors
+considered non-fatal.
