Subject: [2.6 patch] let LOG_BUF_SHIFT default to 17
Date: Tue, 29 Jan 2008 00:12:23 +0200	[thread overview]
Message-ID: <20080128221223.GE8767@does.not.exist> (raw)

16 kB is often no longer enough for a normal boot of an UP system.

And even less when people e.g. use suspend.

17 seems to be a more reasonable default for current kernels on current 
hardware (it's just the default, anyone who is memory limited can 
still lower it).
