I am preparing my series to remove the logbuf_lock, which also refactors and consolidates code from syslog_print_all() and kmsg_dump_get_buffer(). While testing/verifying my series, I noticed the these oddities in the semantics and decided I should research where they came from and if they were actually necessary. I wouldn't say the oddities are necessary (in fact, they are quite annoying), but we have decided to keep them in out of fear of breaking out-of-tree modules and/or interesting userspace code. One positive effect of the rework is that we are finding these oddities and documenting them. I think you and Petr are going down a similar path with the console registration stuff now. John
