[ak at muc.de: Re: [PATCH] kernel/printk.c lockless access]

[Linas Vepstas]

Hi Keith,

I introduced a thread on LKML for adding logbuff access for debugger
use.  I made the patch look as much as possible as the KDB code,
with the direct intention of making things easier for KDB,
although my true intention is to have this be generically useful.

Better&simpler fix would be to just unstatic __log_buf
You cannot call such functions generally when looking at memory
dumps of some form.
