+Subject: [PATCH] do not disable buffer in writing files
+
+Do not disable buffer in writing files, otherwise we get
+failure at boot for musl like below.

+  [!!!!!!] Failed to allocate manager object.
+
+And there will be other failures, critical or not critical.
+This is specific to musl.
+
+Upstream-Status: Inappropriate [musl]
