+Subject: [PATCH 19/19] Do not disable buffering when writing to oom_score_adj
+
+On musl, disabling buffering when writing to oom_score_adj will
+cause the following error.
+
+  Failed to adjust OOM setting: Invalid argument
+
+This error appears for systemd-udevd.service and dbus.service.
+This is because kernel receives '-' instead of the whole '-900'
+if buffering is disabled.
+
+This is libc implementation specific, as glibc does not have this issue.
+
+Upstream-Status: Inappropriate [musl specific]
