Subject: obsolete config in kernel source: BUFFER_DEBUG
From: Christoph Egger <siccegge@xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx>
CONFIG_BUFFER_DEBUG seems to have been removed from the documentation
somewhere around 2.4.15 and seemingly hasn't been available even longer.
It is, however, still referenced at one place from the jbd code (one is a
copy of the other header). Time to clean it up
