+New C code submitted to SLOF should follow the coding style guidelines
+for the Linux kernel [4] with the following exceptions:
+
+- in the event that you require a specific width, use a standard type
+like int32_t, uint32_t, uint64_t, etc. Don't use Linux kernel internal
+types like u32, __u32 or __le32.
+
+New forth code should use 4 space indentations and no tabs. Patches for
+the old code should keep the existing style which usually is
+3 space indentation.
