Subject: [RFC PATCH v4 6/9] printk-rb: adjust test module ringbuffer sizes
Date: Thu,  8 Aug 2019 00:32:31 +0206	[thread overview]
Message-ID: <20190807222634.1723-7-john.ogness@linutronix.de> (raw)
In-Reply-To: <20190807222634.1723-1-john.ogness@linutronix.de>

The ringbuffer documents that the expected average size value
should be lower than the actual average. For the test module the
average should be 64, so set the expected average to 5 bits (32).
