As mentioned in the recent discussion on NFS trace points on the NFS & SystemTap mailing lists. This patch allows field support staff and kernel developers debug kernel problems, by enabling them to treat dprintks as precise trace points rather than syslog spamming tools. 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. 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. Jason Baron suggested I post it here for review and contrast with his dynamic dprintk feature. -- Greg Banks, P.Engineer, SGI Australian Software Group. the brightly coloured sporks of revolution.
