This is a forward ported (from 2.6.16), updated, and split version of a patch that has been used in SGI's internal development tree for the last few months. It's designed to help field support staff and kernel developers debug kernel problems, by enabling them to treat dprintks as precise trace points rather than syslog spamming tools. The very first version of this was used about eighteen months ago when debugging NFS/RDMA, which has an enormous number of dprintks and no other way to debug it. -- Greg Banks, P.Engineer, SGI Australian Software Group. the brightly coloured sporks of revolution.
