An end to jprobes

"Jprobes" are an ancient kernel mechanism used to trace entry into kernelfunctions; they were described in this 2005 LWNarticle. Recently, the kernel community has come to the conclusionthat jprobes have few (if any) remaining users, they have long beensuperseded by the function tracing (ftrace) mechanism, and they are amaintenance burden. As a result, the jprobeAPI will likely be disabled in a near-future kernel. If anybody outthere is still using jprobes, now would be a good time to either move on ormake the case for retaining that feature in the kernel.
