Make struct ring_buf 12 bytes smaller by default. This comes with a 32KB buffer size limit which covers almost all cases. The previous limit of 2GB can be restored with CONFIG_RING_BUFFER_LARGE=y. Signed-off-by: Nicolas Pitre <npitre@baylibre.com>

Provide highly efficient ring buffer management for arbitrary data.

Some facilities such as kernel pipes are built on top of this.

May be used directly e.g. when the pipe overhead is unnecessary.

all struct ring_buf instances become 12 bytes bigger.
